This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
for gcc >= 2.5 and no-ops for gcc >= 2.6. Converted to use __dead2
or __pure2 where it wasn't already done, except in math.h where use
of __pure was mostly wrong.
mount_* programs. While we're at it, collapse the four now-identical
mount programs for devfs, fdesc, kernfs, and procfs into links to
a new mount_std(8) which can mount any really generic filesystem
such as these when called with the appropriate argv[0].
Also, convert the mount programs to use sysexits.h.
- in mount_portal.c: included catching of SIGHUP to get portald to
re-read the config file.
- in mount_portal.c: in SIGCHLD handler the return values checked from
waitpid were wrong. Note. this routine was written correclty according
to the manual page for 4.4BSD, but waitpid does not exhibit this
behaviour. It is not returning 0 when WNOHANG is specified. I havent
checked this properly.
- in mount_portal.c: initialized the fdset for the select properly.
- in mount_portal.c: corrected poor casting in the select.
- in mount_portal.c: changed a break; to exit (0); so that the
children die after doing the hard work, this stops the select: bad
file descriptor messages.
- in pt_file.c: the kernel passes kernel style open flags to the
portal code which aren't compatible with "normal" O_ flags. I have
adjusted these in pt_file.c. In general I think the portal fs code
and portal_cred structure need changing to pass to the portald
the right style of flags _and_ the permissions.
- in pt_tcp.c: a few mistakes in typing of the socket structures,
getservbyname returns the port number as an int but sockaddr wants
the port number as an u_short.
- in pt_tcp.c: someone wrote this on a VAX/Sun whatever and forget
about byte ordering!! I've included a few htons about the place.
- in all the above I have sprinkled a few more debugging printf's.

most common cd9660 and nfs options like God intended them. (It is now
possible to say
mount -o ro,soft,bg,intr there:/foo/bar /foo/bar
again.) This whole getmntopt() business is an incredible botch;
it never should have been anything more than a wrapper around
getsubopt(3). Because if the way the current hackaround is implemented,
options which take arguments (like the old `rsize' and `wsize') are still
unavailable, and must be accessed the new, broken way.
(It's unimaginable how Berkeley managed to screw up one of the few things
about NFS that Sun actually got right to begin with!)
