>Description:
It is fairly common to use tar to archive a living filesystem (a rough way to make a backup)
Unfortunately, when gnu tar consider sockets or accessed files as "bening" errors, ustar/pax
does not and exits with an error 1. This breaks backup scripts.
>How-To-Repeat:
Install gtar from pkgsrc and try :

[xavier@aragorn /]$ sudo tar -cf /usr/tmp/var.tar ./var/ ; echo $?
