On many devices with the A/B partitioning scheme, it is possible to flash postmarketOS to the other/unused slot. The initramfs will find the installation, even if you're currently on the slot with Android.
### Do Flatpak packages, snaps, and AppImages work?
### Can apps be installed from Flatpak?
Flatpak packages — yes! That said, Flathub, the most prominent Flatpak repository, hosts a good deal of nonfree software, and as such Flatpak has similar issues as using Android apps on postmarketOS. In addition to this, many free software Flathub packages are only repackaged pre-compiled .deb files, and consequently it is more difficult to verify what code you're running.
Yes, see the [wiki page](https://wiki.postmarketos.org/wiki/Flatpak) for details.
Snaps may work on edge on non-OpenRC based setups as snapd depends on systemd, support for which was recently added to the edge branch. However, Snaps also have various other issues, including but not limited to the snapd daemon not being available for postmarketOS, Snaps requiring AppArmor(which postmarketOS does not use) and the freedom issues mentioned in regards to Flatpak/Flathub.
### What about Snaps and AppImages?
AppImages do not work as they are linked against the glibc libc implementation while Alpine Linux and postmarketOS use the musl libc implementation. That said, AppImageKit does have plans for some sort of musl support, so this may change in the future. See [issue 1015 in the AppImageKit issue tracker](https://github.com/AppImage/AppImageKit/issues/1015).
Our preferred non-apk app format is Flatpak, so we don't have much interest in supporting other formats.
Snap is not packaged. AppImages [may work](https://github.com/AppImage/AppImageKit/issues/1015).
### Why postmarketOS over ungoogled Android or Halium?
