[systemd-devel] [PATCH] fstab-generator: If we wait indefinitely for a mount, wait also for the device

[harald at redhat.com]

From: Harald Hoyer <harald at redhat.com>

Write out "JobTimeoutSec=0" for the device the mountpoint (which does
not timeout) waits for.

This helps with grabbing a cup of coffee while booting and not have
the crypto password dialog timeout and systemd in a failed state.
