I reassigned the UUID like you said and the problem seems to be solved. These are the values of systemd-analyze now: Startup finished in 4.140s (kernel) + 7.789s (initrd) + 1min 4.993s (userspace) = 1min 16.923s It is the first time that I report a bug (even if it was not a bug after all :) ), now that it is solved there is something that I should do?
