Hi!
Following the Shepherd upgrade in commit
400c9ed3d779308e56038305d40cd93acb496180, attempts to open non-root LUKS
devices from a Shepherd service fail with this cryptsetup message:
Nothing to read on input.
This is because standard input is now /dev/null so it cannot read the
passphrase.
This is because “shepherd.conf” now does:
(start-in-the-background …)
(redirect-port (open-input-file "/dev/null")
(current-input-port))
… meaning that ‘redirect-port’ is now called before services are
started.
‘fsck’ invocations for non-root file systems (started from Shepherd
services) would have the same problem.
I’ll try and come up with a solution…

Fixed with these commits:
f239b9d788 tests: Add "encrypted-home-os" installation test.
dcb0e54a4f file-systems: Invoke fsck tools with 'system*/tty'.
931f13840b mapped-devices: Ensure 'cryptsetup open' gets a tty.
