>Description:
The following enhancements to the pkgtools/mksandbox would be useful:

* Check to see if the sandbox is already mounted before mounting it
  again.  (Mounting the sandbox on top of itself is just messy, and
  awkward to unwind!)

* Don't try to unmount the sandbox if it is not already mounted.

* In addition to --rodirs and --rwdirs, provide for --tmpdirs.  This
  would allow, for example, --tmpdirs tmp=tmpfs[:-m1777,-sram%25] to
  mount a tmpfs on /sandbox/tmp with the listed (optional) options.
  This is an alternative to including /tmp in the list of --rwdirs.
