That applies to RTLinux in special, as it would be rather fatal
if RT-Tasks are swaped out :-)


recently, i tried linux on a 386SX16 with 2MB RAM (no swap-space) and
nfsroot. 2MB are sufficient for simple services (as likely many rt-linux
tasks are). But you have to do some handicrafts to reduce memory,
expecialy, you have to get rid off SysV-init and only allow
one shell or start you user-space-application directly from the
init-process.

I yet didn't tried rtlinux with 2MB, but it should be ok as well
(rtl doesn't need much memory - depending on your rt-application,
of course)
