The upgrade process is tested as part of release criteria, and if it doesn't work it is release blocking. But there's always a need for more testing of such things to find the edge cases. And the difficulty there is most of that testing is done on cleanly installed n-1 version. Not as much testing happens on aged n-1 systems before running the n version upgrade. A conservative approach would be to tar up /boot and then snapshot the 'fedora-root' LV before doing the upgrade (or for Btrfs users tar /boot and then snapshot the 'root' subvolume). I guess the drawback is conventional LVM snapshots is that they are tedious to use: you have to have free space in the VG already, which is not a Fedora installation default, so that the CoW changes to the original volume during the upgrade have somewhere to go, it's slow, and you have to commit or reject changes at some point which is also confusing (to me anyway). LVM thinp snapshots and Btrfs snapshots are way easier to work with, with LVM thinp LV's totally obviating any future need to shrink a file system as well - just fstrim it and any unused logical extents are returned to the VG for reallocation to any other LV. Or the conservative conventional approach is to back it all up and be prepared to restore it if it goes badly. So I'd say I'm closer to opinion 1 than opinion 2. -- Chris Murphy -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://lists.fedoraproject.org/admin/lists/users@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
