For reasons which I won't go into now my encrypted home partition was

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.
