I'm confused here. We're discussing cases where /usr gets mounted twice.
It's getting mounted twice from the same filesystem?

Isn't this a bug in mount? To quote the man page (from my infamous i386
snapshot :-)


     -a      Similar to the -A flag, except that if a file system (other than
             the root file system) appears to be already mounted, mount will
             not try to mount it again.  Mount assumes that a file system is
             already mounted if a file system with the same type is mounted on
             the given mount point.  More stringent checks are not possible
             because some file system types report strange values for the
             mounted-from device for mounted file systems.

Shouldn't mount be avoiding this anyway?

Or am I way low on clue this morning?

Take care,
