Not only that, but if you like, you can easily give `bin' uid 0 so that
the files are really owned by root.

The `-m 755' (I use `-m 555' for shell scripts, just so no one edits
the `binary' version of the script) is another matter; it might be nice
if install defaulted to not ignoring the umask.  (Perhaps -m should
set the mode to arg&~umask(), while -M would set the mode to arg, so
that some Makefiles could explicitly override the umask.  Or perhaps
they should be symbolic: `-m x' for ordinary binaries, `-m rx' for shell
scripts.)  In any case, I would be happier if this information were
in only one place, rather than being duplicated throughout every
makefile in /usr/src.
