Can confirm @kmputerguy's report. Seen this bug on multiple hardware configurations, it basically renders the rescue mode useless for involved maintenance operations.

After ~120 seconds, systemd sees a timeout and starts another "friendly-recovery" whiptail process. This and the running shell now compete for tty access (input and output) thus making the shell nearly unusable. Diagnosing this, it becomes clear that in the first root shell entered from friendly-recovery, "systemctl list-jobs" lists the generated "wait for disk" tasks for the /boot partition and the swap partition still to be running. Only when they run into a timeout, the next friendly-recovery is spawned. I'll attach a log session for such a boot that has two manual "logger" entries in it: Feb 06 10:54:57 harry root[605]: now in root shell from friendly-recovery ... Feb 06 10:56:41 harry root[1254]: now running in parallel This clearly shows the timing of the startup. I have no idea why the "wait for disk" units run into a timeout as the system boots correctly in the "non-rescue" mode. I'll further attach a "systemd-analyze blame" from a regular bootup to show that there is no trace of such a timeout to be found. Furthermore i do have this behaviour on a real machine and on an (independent) VM, so affects more than the machine the bug was reported from.
