Testing repos: systemd-249rc2-1 unable to boot

With the testing repos, systemd 249rc2-1 seems to be unable to boot.
I downgraded to previous systemd 248.3-2 and it works OK.

249rc2-1 also OK here.

Is there any log/output/journal entry that points to anything?

Working here also on Plasma.

Finally had some time to figure this out, or at least a workaround.
New systemd 249 seems to have changed how it interprets some stuff in /etc/fstab.

I used to have this line in /etc/fstab for a USB stick:

LABEL=XYZ  /XYZ ext4 defaults,nofail

and it worked without issue with older systemd 248.x.
But with systemd 249 it waited about 2 minutes for this USB stick before booting. The USB stick was not connected, and option nofail does not help in systemd 249, as it did with 248.

Now I changed the line to:

LABEL=XYZ  /XYZ ext4 defaults,nofail,x-systemd.device-timeout=1ms,x-systemd.automount

and the system works again as expected with systemd 249.

Maybe this is documented somewhere in systemd 249 …


As a side note, you shouldn’t need nofail with x-systemd.automount. systemd automounts are mounted on demand. They don’t block things.

Thanks, I agree, will try that.

By the way, the reason revealed itself by simply removing the quiet kernel parameter. Obvious troubleshooting method in hindsight. :wink:
