Just the risk your parent system dies which will block your access to the child file system mounted on a mount point within. If that is not bothering , go ahead mount stacks . As for the symling though : it is also gone if the parent dies :-).

This has all the hallmarks of either a Windows admin or a newbie Linux/Unix admin :-) Simply put /projects is mounted on top of whatever file system is providing the root file system in the first place LOL. Linux/Unix and/or GPFS does not give a monkeys about mounting another file system *ANYWHERE* in it period because there is no other way of doing it. JAB. -- Jonathan A.
