[TUHS] SVR2 on a PDP-11

[Henry Bent]

Hello all,

I have a distribution of SVR2 on the PDP-11 that I have managed to get
booting into the initial root dump, but it is not clear to me how to
proceed from there to format a /usr filesystem and setup for multi-user.
The root dump boots on a simulated 11/70 with an RP06:

--
sim> boot rp
#0=unixgdtm

UNIX/sysV: unixgdtm
real mem = 3145728 bytes
avail mem = 3068864 bytes

INIT: SINGLE USER MODE
--

I'm mostly a BSD person but I'm familiar enough with some later SysV
systems.  That being said, the initialization procedure here is completely
foreign to me.  I have cpio files for the entire system and I know in
theory how to extract them, but I'm stuck at the basics of creating /usr,
setting up /etc and the like.  I have a fully extracted filesystem from the
cpio files that I can browse but I can't find enough information in the
manpages.  I haven't managed to find any installation manuals or the like
on Bitsavers, and I can't even manage to find a listing in the source of
the expected disk partitions/sizes.  I feel very much like I am stumbling
in the dark here and would appreciate any pointers to how to proceed.
Thanks!

-Henry
