The confusing part may be the implicit bind that happens
when you do
bind -ca /sys/src/cmd $home/kern/cmd
The resulting mount point has to things in the link
list bound there:
/sys/src/cmd - containing the create flag
$home/kern/cmd - not containing the create flag
The latter is implicit since you were binding -a onto a
directory. You would have gotten the semantics you
wanted if you had said instead:
bind -c $home/kern/cmd $home/kern/cmd
bind -ca /sys/src/cmd $home/kern/cmd

union directories are a linked list.
- open finds you the first file in the list bound directories,
in the order they were bound [before/after]
- create choose the first directory which allows creation,
in the order they were bound [before/after]
the order they were bound is not temporal, it's where you bind them.
it's that easy.
