пишет: After performing an update to the latest tumbleweed snapshot, an oss 13.2 tumbelweed So is it 13.2 or is it tumbleweed?
machine with BTRFS for / mount root as ro at bootup. There are no errors logged anywhere regarding that, and the filesystem is all good. / can be remounted as rw post bootup just fine, problem is it is not happening automatically. Where do I need to look to troubleshoot, I am a bit lost with all the systemd material all over the place.
What does "systemctl status systemd-remount-fs.service" say?
Thanks Andrei.
Apologies, it is tumbleweed.

Andrei, since you were kind enough to point me to the systemd-remount... unit, I did some digging and realized it uses /etc/fstab. This machine has ~no~ fstab at all (not sure why an upgrade - zypper dup - would have deleted it). Well ... then remount-fs service cannot really know which options to apply. In this case you should ensure initrd mounts you root filesystem with intended options. I do not know if openSUSE with empty fstab is really supported.
Well, thanks to snapper (I think that is what takes snapshots at boot time), I had snapshots going back quite a ways and I found a perfectly good fstab from an older snapshot, copied it to /etc/, and now all is good. Thanks again Andrei for leading me down the right track. Just FYI, the system ran fine without the fstab, except that I had to remount / as rw after each bootup.
