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). Can I simply copy /etc/mtab to /etc/fstab?

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.

Hrmmm... what's going on here... currently fstab is completely optional..as long you specify the root device in the kernel command line with the appropiate flags..

systemd initially mounts root "ro" unless you explicitly specify "rw". YaST does not add "rw". Sure, everything is possible manually as long as you know which knobs to push, but right now in default configuration openSUSE without fstab will not remount root rw. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
