For reasons which I won't go into now my encrypted home partition was obliterated. (Yes, all the data thereon had been backed up.) I created a new one, but of course it does not have the same UUID as the previous one. Jessie's systemd however on boot continues to look for the old UUID for that partition. Consequently the encrypted home partition can no longer be opened during the boot. I would be grateful if anyone can tell me where the UUIDs of the encrypted partitions to be opened on boot, such as tmp and home, are stored so that systemd can find them during the boot?
After some research I found file /etc/crypttab which contains a list of the UUIDs for encrypted partitions, /home in my case. I thought it would be a simple matter of changing the relevant UUID to the current one. It is apparently not.
I found a reference to systemd-cryptsetup-generator, the manual for which makes reference to further steps which I do not understand. Systemd-cryptsetup-generator does not seem to be a command.
After changing the relevant UUID in the crypttab file I discovered that a reboot caused the /home directory to be opened without my entering the passkey. The computer however did not go on the install the DE; instead it went to recovery mode.
