Some years back iX tried to release a FreeBSB distro called TrueOS. (It was originally called PC-BSD or PCBSD.) It did not get wide spread adoption. Checking, development stopped around 2020.
One thing that I really wanted was less painful updates. Using alternate boot environments make that easier since if an update does not perform well, a simple reboot to the prior BE solves that problem.
Their are multiple ways to do BEs;
- Separate physical partitions
- Extra LVM partitions
- BTRFS snapshots & clones
- ZFS snapshots & clones
I’ve personally used 3 of those at home, (not the LVM one), and found that ZFS was the best. (I did a proof of concept for the LVM, it will work…)
Recently I’ve even experimented with live updates to a clone using chroot. Kinda tricky to both setup and make updates, but could be made more automated.
So, how about a Debian based distro that includes OpenZFS with easy alternate boot environments for updates?
Perhaps with a good installer that does ZFS on root, possibly with encryption?
Their are few Linux distros that support boot to ZFS and root FS on ZFS.
