[TUHS] SVR2 on a PDP-11

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
