A system service should NOT have a home directory in /home so all of the
UIG/GID in /home should be above 500.
That's irrelevant. If it creates files in (say) /var as whatever user it
picks at random, and then I copy my old password file over the new one, it
will be All Br0ke. (And that's not even considering the annoyance of dealing
with any *new* system users.)
system accounts should not have home directories in /home anyway.
I have no idea why you're all on about /home.
But really - just like you need to preserve your ssl keys, a
should preserve /etc/passwd and /etc/group. I never personally
save /etc/shadow - I just use the saved /etc/passwd to recreate users
keeping uid/gid the same.
See above. :)
