With 'e' pressed at boot menu, I set the `root=UUID=[wrong UUID]` in boot cmdline. Then I expect that I will run into emergency mode.However, boot log stuck at `Job dev-disk-by\x2duuid-XXXX-device/start running(5min 10s/ no limit)`. I tried DefaultDeviceTimeoutSec=90s, but it doesn't work.
In addition, if I set a wrong uuid of root device in fstab, the system will boot up with read-only filesystem instead of running into emergency mode even if I didn't set 'nofail'. Is there any way that I can set the timeoutsec or how can I run into emergency mode if root device is set incorrectly?
