Be aware the sandbox of flatpak is not safe for web browsers, specially firefox based browsers:

omg I cannot fucking believe that while I was typing this I just saw another distro package nonsense:

There is this very good tool called soar which I use for static binaries. (It also has support for appimages but to be honest it is not as good as AM rn).

Well we just got a complain that fastfetch is not displaying the package count of soar, which fastfetch is able to do.

Turns out this is because the archlinux package is built without SQLITE3 which is needed for that feature to work 😫

And what’s worse is that account registrations are disabled in the archlinux gitlab, so I have to jump thru some hoops to get a basic bug report filed…

I want full-scale applications that are so big they have to use system libraries to keep their disk size down

Linux is in such sad state that dynamic linking is abused to the point that it actually increases the storage usage. Just to name a few examples I know:

most distros ship a full blown libLLVM.so, this library is a massive monolith used for a bunch of stuff, it is also used for compiling and here comes the issue, by default distros build this lib with support for the following targets:

-- Targeting AArch64
-- Targeting AMDGPU
-- Targeting ARM
-- Targeting AVR
-- Targeting BPF
-- Targeting Hexagon
-- Targeting Lanai
-- Targeting LoongArch
-- Targeting Mips
-- Targeting MSP430
-- Targeting NVPTX
-- Targeting PowerPC
-- Targeting RISCV
-- Targeting Sparc
-- Targeting SystemZ
-- Targeting VE
-- Targeting WebAssembly
-- Targeting X86
-- Targeting XCore

Gentoo used to offer you the option to limit the targets and make libLLVM.so much smaller, but now rust applications that link to llvm have issues with this with caused them to remove that feature…

Another is libicudata, that’s a 30 MiB lib that all GTK applications end up linking to for nothing, because it is a dependency of libxml2, which distros override to build with icu support (by default this lib does not link to libicudata) and what’s more sad is that the depenency to libxml2 comes because of transitive dependency to libappstream, yes that appstream that I don’t even know why most applications would need to link to this.

And then there is archlinux that for some reason builds libopus to be 5 MiB when most other distros have this lib <500 KiB

Sure dynamic linking in the case of something like the coreutils, where you are going to have a bunch of small binaries makes sense, except you now have stuff like busybox which is a single static bin that acts as each of the different tools by checking the name of the symlink that launched it and it is very tiny at 1 MiB and it provides all your basic unix tools including a very good shell.

Even Linus was surprised by how much dynamic linking is abused today: https://lore.kernel.org/lkml/CAHk-=whs8QZf3YnifdLv57+FhBi5_WeNTG1B-suOES=RcUSmQg@mail.gmail.com/

To pick how I’m going to install something,

https://github.com/ivan-hc/AM

I have all these applications using 3.2 GIB of storage while the flatpak equivalent actually uses 14 GiB 💀: https://i.imgur.com/lvxjkTI.png

flatpak is actually sold on the idea that shared dependencies are good, you have flatpak runtimes and different flatpaks can share, the problem here is that those runtimes are huge on their own, the gnome runtime is like 2.5 GiB which is very close to all those 57 applications I have as appimage and static binaries.

but it doesn’t actually make it easier for me, it just makes it easier for the packager of the software

Well I no longer have to worry about the following issue:

• My application breaking because of a distro update, I actually now package kdeconnect as an appimage because a while ago it was broken for 2 months on archlinux. The only app I heavily rely from my distro now is distrobox.

• I also get the latest updates and fixes as soon as upstream releases a new update, with distro packaging you are waiting a week at best to get updates. And I also heard some horror stories before from a dev where they were told that they had to wait to push an update for their distro package and the only way to speed it up was if it was a security fix.

• And not only you have to make sure the app is available in your distro packages, you also have to make sure it is not abandoned, I had this issue with voidlinux when I discovered the deadbeef package was insanely out of date.

• Another issue I have with distro packages in general is that everything needs elevated rights to be installed, I actually often hear this complains from linux newbies that they need to type sudo for everything and it doesn’t have to be this way, AM itself can be installed as appman which makes it able to work on your HOME with all its features. And you can take your HOME and drop it in any other distro and be ready to go as well.

AppImage is meant to be updated using the embedded zsync info the runtime, that is the user should never have to open the app to update it.

The user needs to have something like AM, appimagelauncher or appimaged that is then able to parse the info and update the appimages using appimageupdatetool

This method also provides delta updates, meaning it doesn’t download the entire app but only a diff, see this test with CPU-X where it downloaded 2.65 MiB to update the app:

appimaged does exactly that automatically for you.

With that said I prefer AM, because it also adds the applications to PATH, meaning you type yuzu on the terminal and it launches yuzu as well.

Or even just Flatpak.

AM was started because flatpak sucks.

• With flatpak devs can’t agree to use a common runtime, so the user ends up with a bunch of different runtimes and even EOL versions of the same runtime, making the storage usage 5x more than the appimage equivalent and this is much worse if you use nvidia which flatpak will download the entire nvidia driver again.

• flatpak could not bother to fix the hardcoded ~/.var directory, something that AM fixes by simply bind mounting the existing application config/data files to their respective places when sandboxing which yes it is able to sandbox appimages with aisap (bubblewrap).

• flatpak threw the mess of handling conflicting applications to the user, so you have to type nonsense like flatpak run io.github.ungoogled_software.ungoogled_chromium, AM just puts the app to PATH like everyone else does, even snap doesn’t have this issue.

Be aware librewolf and all firefox based browser have security issues with flatpak because flatpak by forcing seccomp filtering breaks the internal sandbox of the browser:

https://librewolf.net/installation/linux/#security

Not to mention the librewolf flatpak is literary the portable tarball they release that works on your distro already, in other words it is the worst way possible to use librewolf.

And you only get that “ease of use” of being able to install it in the software store with one click because your distro did the pain of installing and configuring flatpak for you, otherwise it would have been much worse than what you posted.

Anyways, try using appman instead:

wget -q https://raw.githubusercontent.com/ivan-hc/AM/main/AM-INSTALLER && chmod a+x ./AM-INSTALLER && ./AM-INSTALLER

And then: appman -i librewolf which will “install” the AppImage and you can also sandbox it with am --sandbox librewolf and this sandbox does not break the internal sandbox of the browser unlike flatpak.

AppImage isn’t a good comparison for a lot of different reasons

Alright what does flatpak offer in this case?

• Has performance issues 1

• The thing is not XDG Base dir compliant 1 2

• Has security issues even 1 2 3 and not to mention the whole bunch of flatpaks that use EOL runtimes which are even worse, not only for security, but also because that single flatpak ends up pulling an entire runtime for itself which makes even more bloated.

• And is insanely bloated as you saw already.

I think enough people have summarised that on the internet by now.

Such as? but I likely know already what is going to be said, hopefully is none of the following:

• “Depends on libfuse2” (not true since 2022 with the static appimage runtime, this also allows making appimages that work on musl systems, which several like ghostty, goverlay, Steam, gimp, cromite, citron already do)

• “You need to build on an old distro and it is hard”, once again not true anymore since you can now bundle the glibc as well (and it is needed for appimages to work on musl systems).

• “No wayland”, this is only true if you use linuxdeploy-qt to make the AppImage, the project has been abandoned already for several years and the only project I know that still uses it is qbittorrent-enhanced.

EDIT: And also hopefully you are aware that a lot of flatpaks are literary an AppImage shipped in a flatpak runtime, like:

• https://github.com/flathub/dev.vencord.Vesktop/blob/master/dev.vencord.Vesktop.yml#L34-L46

• https://github.com/flathub/com.ultimaker.cura/blob/master/com.ultimaker.cura.yml#L24-L44

• https://github.com/flathub/xyz.armcord.ArmCord/blob/master/xyz.armcord.ArmCord.yml#L40-L43

• https://github.com/flathub/com.heroicgameslauncher.hgl/blob/master/com.heroicgameslauncher.hgl.yml#L191-L196

• https://github.com/flathub/chat.simplex.simplex/blob/master/chat.simplex.simplex.yml#L22-L31

• https://github.com/flathub/menu.kando.Kando/blob/master/menu.kando.Kando.yml#L33-L40

So yeah AppImage isn’t ideal, lets ship it in a container anyway 😁

and through deduplication between different runtimes and runtime versions. There’s usually very little bloat, if any, especially if you use Flatpaks a lot,

~20 different GUI applications, flatpak ended up using 14 GiB of storage while the appimage equivalent used 3.2 GIB.

And note I was not able to find flatpaks for ghostty, goverlay, kdeconnect and a few other apps, meaning the actual bloat of flatpak is even higher.

Edit: And this is even worse if you are an nvidia user, flatpak will download the entire nvidia driver as well.
