I have a script for doing it - though only within a single user...
This is the core of the link logic:
print "fixing up files for $guid ($srcname)\n";
foreach my $file (@others) {
my $tmpfile = $file . "tmp";
print "link error $tmpfile\n" unless link($srcname, $tmpfile);
chown($uid, $gid, $tmpfile);
chmod(0600, $tmpfile);
print "rename error $file\n" unless rename($tmpfile, $file);
}
I suspect your fixup is similar :)
