Hey, thanks Guys! Ok, good that the kernel already knows about it.
The actual problem I'm having is that ps doesn't work.
I assume it tries to look at /dev/swap as its pointer, but since there's
no /dev/rl0a, dev/swap has nothing reasonable to point to, so ps fails with
/dev/swap: no such device (iirc).
Was thinking of experimentally linking /dev/swap to rl0 but logic
dictates that would trash the root filesystem (which is nbd since I can
easily restore the 2.9 rl02 root from the archives with Warren's vtserver!)
Gonna go read some source. Thanks!

I'm having trouble understanding how to get
my swap configured. Since
rl02s are so little, the MAKE file in /dev doesn't partition them
into
a, b, c, etc. However, when MAKE makes the
/dev/rl0 device, it uses
only 8500 of its 10000 blocks, so what would presumably be intended
as
swap space does exist. Swap is usually linked to
the b partition,
right? So how do I create this b partition on an rl02?
I don't know how the later systems work, but in V6, the swap device, and
the
start block / # of blocks are specified in the c.c configuration file (i.e.
they are compiled into the system). So you can take one partition, and by
specifying less than the full size to 'mkfs', you can use the end of the
partition for swap space (which is presumably what's happening with
/dev/rl0
here).
