Should we make these system accounts no-login accounts, and set the set
their shells to /bin/false to prevent any latent issue?

For example, my distro's passwd has:
    sshd:x:115:65534::/var/run/sshd:/usr/sbin/nologin
    nobody:x:65534:65534:nobody:/nonexistent:/bin/sh

and shadow has:
    sshd:*:15767:0:99999:7:::
    nobody:*:15630:0:99999:7:::

So, setting at least the shell to /bin/false would be better.

Also, why do we have an sshd user to begin with? We already had this
discussion about the 'mail' user, but 'mail' is in the low-digits, and
very traditional to UNIX. 'sshd' on the other hand is above 100, and
is not really needed: the ssh server should run as root to allow logins
anyway.

And since packages can now create users... ;-)

Should we prepare to claen up etc/passwd (and associated files)?
