My /etc/fstab intentionally has quite a few entries that point to (labelled) partitions and filesystems that may not be present at boot time (think: hotpluggable SATA backup disks).
These entries cause trouble during boot because I get trapped for 1min30sec (90sec) while some boot process waits for these disks or partitions to appear. The wait is accompanied by the well-known message "A start job is running for dev-disk-by" and a countup to 1m30sec.
Question: I would like to CHANGE the timeout value from 90sec to, say 10sec, so that boot and shutdown will go faster. How do I do that?
Status: I have looked high and low for the proper parameter to set. One thing I tried was to add some kernel parameter values to the appropriate grub.cfg line, as follows, but it had no effect.
udev.event-timeout=10 rd.udev.event-timeout=10 udev.exec-delay=10 rd.udev.exec-delay=10
