This may be more of a general linux question but is there a simple way of preventing users from creating symlinks to or from certain directories? I have a /scratch dir that's a single 27TB volume and I don't want users linking their home dirs as there's a chance it will screw up our external backups. Is this a job for SELinux? Any ideas?
Thanx,
Russell

Can't your backups simply ignore symlinks? Or (more sensibly) backup the symlinks as links, instead of dereferencing them?
Perhaps SELinux can do what you want, but it seems like overkill compared to telling the backup program what to backup (and what not).
