That doesn't solve the problem of executable DEINSTALL scripts....
If I have a separate /var that's mounted noexec I might also have a
separate /pkg/var that's also mounted noexec.
Note that setting TMPDIR to an appropriate value in pkg_add's
environment solves the problem of executable INSTALL scripts if /tmp is
mounted noexec. The same doesn't work for DEINSTALL scripts of course,
unless maybe pkg_delete were modified to copy the program to TMPDIR
before trying to execute it.
You probably want to set root's TMPDIR to a secure private area
