Worth mentioning aside Alpine (and other small Linuxes) supporting ZFS just fine, we also have ZFSBootMenu, which is frankly a hell of a lot better than the boot environment experience in FreeBSD. https://docs.zfsbootmenu.org https://docs.zfsbootmenu.org From within the bootloader's interactive (fzf-based) menu, you can: * Select boot environment (and change the default boot environment) * Select specific kernels within each boot environment (and change the default kernel) * Edit kernel command line temporarily * Roll back boot environments to a previous snapshot * Rewind to a pool checkpoint * Create, destroy, promote and orphan boot environments * Diff boot environments to some previous snapshot to see all file changes * View pool health / status * Jump into a chroot of a boot environment * Get a recovery shell with a full suite of tools available including zfs and zpool, in addition to many helper scripts for managing your pool/datasets and getting things back into a working state before either relaunching the boot menu, or just directly booting into the selected dataset/kernel/initrd pair. It also supports 100% of ZFS features that the host system supports, since it uses the ZFS kmod. That includes native encryption.

I have seen what ZFSBootMenu can do and I really like it. Its just 'crazy' to me that there are ZERO Linux distributions that install as root on ZFS with ZFSBootMenu and enabled ZFS Boot Environments. None. Zero. Why?

  They're afraid of the hypothetical legal threat from Oracle, which largely seems to come from a lot of license misinterpretation and urban myth. Seems like the only ones that have ventured to ship a ZFS binary are Canonical, and their implementation seems to be done by people that didn't understand ZFS and have no interest in understanding it. It's really a shame. OpenZFS on Linux really has excellent support and integration, arguably as good as or better than FreeBSD and Illumos, and has this excellent bootloader. Still, ZFS has good out-of-tree support in distros like Void and Alpine, where the users can take it upon themselves to do a good root-on-ZFS setup and reap the benefits.

    The iXsystems do that in TrueNAS SCALE on Debian Linux. Here: - https://i.imgur.com/c4WUwb1.png https://i.imgur.com/c4WUwb1.png Unfortunately there is no command like bectl(8) or beadm(8) to manage that. You have to do that from the WebUI: - https://i.imgur.com/2JhZ6VB.png https://i.imgur.com/2JhZ6VB.png Hope that helps.
