# Note if a group is not specified, install(1) will assume that a file
# would be installed with the current user's group ID, and thus if the
# file is the same except that it does have a different group due to
# its parent directory being g+s for example, then the copy will be
# done again redundantly in a futile attempt to reset the group ID to
# that of the current user.

# install -d -g wheel -m 2775 test # Create setgid dir
# touch test/a # Create source
# install -Cv -m664 test/a test/i1 # install source with mode
# install -Cv -m664 test/i1 test/i2 # install dest
# install -Cv -m664 test/i1 test/i2 # again to see redundant install
#
# Similarly if an existing file exists that is the same and has the
# current users group ID, but when an actual install of the file would
# reset to a different group ID due to the directory being g+s for example,
# then the install will not be done when it should.

# install -Cv -m664 -g "$(id -nrg)" test/i1 test/i2 # set i2 to uesr's gid
# install -Cv -m664 test/i1 test/i2 # this should install but doesn't

# Therefore we skip the test in the presence of setgid dirs
# An additional complication on HFS is that it...
