[PATCH] etc/daily - handle purging accounting records a bit better

[Raf Czlonka]

Hi all,

I've enabled accounting recently and have noticed these messages
in the daily(8) email:

Day 1:

        Purging accounting records:
        mv: /var/account/acct.2: No such file or directory
        mv: /var/account/acct.1: No such file or directory
        mv: /var/account/acct.0: No such file or directory

Day 2:

        Purging accounting records:
        mv: /var/account/acct.2: No such file or directory
        mv: /var/account/acct.1: No such file or directory

Day 3:

        Purging accounting records:
        mv: /var/account/acct.2: No such file or directory

These could be silenced by a simply testing if a particular file
exists before trying to rename it.

Regards,

Raf
