/etc/passwd->shell

["\"Ivan R.\"" <ivan.rambeau@franceonline.fr>]

hi all!

i want a password file
without hole.

so i have now in /etc/passwd:

root with /bin/bash
daemon, bin and sys with /bin/sh
sync with /bin/sync
normal users with /bin/bash
ftp users with /bin/noshell

here i think that s good

but i have some questions :

what about replace /bin/sh for man by /bin/false?
i tried and to see man pages that s ok.
is there a reason to let /bin/sh?

why mail and www-data has got /bin/sh
and not mysql (/bin/false)?
why no shell for mysqld and shell
for the others?
what should i do here?

thanks in advance for all

;D
