Comment 23 for bug 325690

Interesting, I followed a different guide when setting up my lvm+cryptsetup system and I have not had an issue with initrds not containing cryptsetup, -except- once when I used -u instead of -c to run update-initramfs.

This was an upgrade from an 8.10 system.

Are there any tests/details you might want? Does anyone still have problems with failure for booting with no prompt for a cryptsetup password?
