[systemd-devel] transient hang when starting cryptography setup for swap

[Chris Murphy]

This is still a bug on Fedora 30. I can only reproduce it on one
computer, I'm not sure why.

The working case

[   23.310555] flap.local systemd[1]:
dev-disk-by\x2duuid-dcae3053\x2d1cc2\x2d4890\x2da33b\x2d6d71b3dc97df.device:
Changed dead -> plugged
[   23.310639] flap.local systemd[1]:
dev-disk-by\x2did-dm\x2dname\x2dcryptswap.device: Changed dead ->
plugged
[   23.310681] flap.local systemd[1]: dev-mapper-cryptswap.device:
Changed dead -> plugged
[   23.310724] flap.local systemd[1]: dev-mapper-cryptswap.device: Job
165 dev-mapper-cryptswap.device/start finished, result=done
[   23.310765] flap.local systemd[1]: Found device /dev/mapper/cryptswap.

In the non-working case, that never happens. systemd just doesn't see
the swap device appear. But in early debug shell, 'blkid' sees it.
