anyway, I think we just need to add after = ["cryptsetup.target"];, which I could swear we already had :P

In reply to @lily:lily.flowers
If I don't enter password it times out on the mapper device though

In reply to @copadium:matrix.org
should I add that and re-test?

Lily Foster: In my test with ext4, I'm not getting such a timeout

In reply to @elvishjerricco:matrix.org
in fact, when I finally decided to enter the passphrase, the little "waiting for..." message about the mapper device showed up for a second, saying it had been waiting for 9mins, so that definitely doesn't time out :P

dev-nixos-root.device is what is timing out for me (trimmed snippet of relevant journal log section):

Should I be concerned if I see "Stopping Rule-based Manager for Device Events and Files" take upwards of 15 seconds on startup? Maybe relevant section of journalctl --boot=0 logs:

I see the "Stopping" and "Stopped" timestamps are within 6 seconds of each other, but I swear I see the little moving red *s for substantially longer than that on startup
