a union mount.
eg.
src: FORCE
FORCE is a fake target that does not have sources. When FORCE is
considered made it gets updated with the current timestamp. If the
directory happens to have the same timestamp too, then it will not
be made because it is considered to be up-to-date with respect to
the child. This can happen because the time resolution is only in
seconds. It is more likely to happen on a union filesystem where
the timestamps take longer to update.
The fix is to consider the parent unmade when children have been
updated.
- cpu_set_kpc() now takes void *arg third argument, passed to the
entry point.
- cpu_fork() allows parent to be non-curproc iff parent is proc0.
When forking non-curproc, assume its state has already been saved.
- Adjust various pieces of machine-dependent code to account of all of this.

in the future):
- New function, fork_kthread(), takes entry point, argument for entry point,
and comment for new proc. May be called by any context, will fork the
thread from proc0 (requires slight changes to cpu_fork()).
- cpu_set_kpc() now takes a third argument, a void *arg to pass to the
thread entry point. Thread entry point now takes void * instead of
struct proc *.
- Create the pagedaemon and reaper kernel threads using fork_kthread().
(find_dummy_reload): New parameter earlyclobber. If set then don't
use IN for the reload if it also appears elsewhere in the insn. All
callers changed.
This fixes problems compiling editors/emacs and games/abuse on the Shark.
client programs are allowed to finish up (coda_call is
forced to complete) and release their locks. Thus there
is a reasonable chance that the vflush implicit in the
unmount will not get hung on held locks.
non-soft-settable media. Treat that as if there was no media output.
Use a supplied media-string of "<null>" or "<default>" or synonyms to
avoid passing explicit media flags onto ifconfig.
