Memory file system





1.  General notes

While ramfs is pretty fast, it's not optimal since it's	sin-
gle  threaded.	 By  default  it has a maximum size limit of
768MB, if you need more, pass  -p flag.	 It also can end  up
filling	your memory very quickly. be careful.

2.  using ramfs	instead	of /tmp	by default

To use ramfs by	default	for /tmp, replace these	two lines in
$home/lib/profile:

  if(! syscall create /tmp/xxx 1 0666 >[2]/dev/null)
	  ramfs	  # in case we're running off a	cd

With these lines:

  ramfs
  bind /tmp /usr/$user/tmp

a use case would be if you don't want to use disk.
