[BackupPC-devel] Inherited patch question

[Richard S. <hob...@gm...>]

I'm working on the 4.1.0 release for Fedora and I've been working through
all the patches I inherited, most of which aren't necessary anymore.

Here's one that I'm not sure what effect it actually has:

$ cat rpmbuild/BackupPC/SOURCES/BackupPC-4.0.0-fix-shadow-access.patch

 This script needs to run as the user specified in \$Conf{BackupPCUser},
 which is set to $Conf{BackupPCUser}.

            . " ($bpc->{Conf}{BackupPCUser})\n");
        print(STDERR "Please su $bpc->{Conf}{BackupPCUser} first\n");

What's the effect of removing the [2] from these?

Thanks,
