You mount the server into that path. Remember, a server advertises a port
number; it is not connected with a particular filesystem path. A client can
then choose to attach a server to a portion of its address space.

For you case, I would do:

$ mount srv/joystick /dev/mouse

The "stat" command will get the file attributes in field=value format. You
can then use "stat -w field=newvalue". For DOS, you can rewrite the
read-only protection, the modified/created time, and the file type
(switching from symlink to regular file, which actually just toggles the
hidden bit).

"swapd -n" will run the swap daemon with no swap partitions. This will just
reclaim pure pages. Until the next release, this page stealing will not
find many pages which could be reclaimed.

"swapd disk/wd:wd0_lxswap0" would start swapping using a Linux swap
partition on the first IDE disk.

Swapping has become more robust, but still plan on doing kernel debugging if
you enable it and use it much.
