I use FreeBSD for my NAS/utility server at home, and am considering switching over to Linux now that ZFS seems pretty stable there. NixOS is my happy place these days.
For personal it’s probably fine but I wouldn’t use it in prod again.
Debian ZFS is not easy to install as root FS which is .. disappointing. It would be nice if it was integrated into the net install .iso as a legit disk install option.
I’ve run it on Ubuntu for at least 5 years without issue.
