The offending bits are in Ben's script :
sub update_symlink {
my ($source, $dest) = @_;
$source = File::Spec->abs2rel($source,
(File::Spec->splitpath($dest))[1]);
# Don't make unnecessary changes
my $old_source = readlink($dest);
if (defined($old_source) && $old_source eq $source) {
return;
}
# Create a symlink with a temporary name
my $rand;
while (($rand = int(rand(1000000))) && !symlink($source,
"$dest.$rand")) {
if ($! != POSIX::EEXIST) {
die "Failed to create symlink to $source: $!";
}
}
# Move it into place atomically
if (!rename("$dest.$rand", $dest)) {
my $err = "$!";
unlink("$dest.$rand");
die "Failed to create or replace $dest: $err";
}
print "I: $dest is now a symlink to $source\n";
}
Easy to fix manually if I can figure out what was supposed to be
symlinked from where to where.
I question the use of 'rand' to create a temporary file name but that
is another issue.
