I'm creating an automated ITS install, starting from tapes, and building
as much as possible from source code.
At first, I loaded everything - binaries and source code - onto a fresh
disk using NSALV. This worked fine in the beginning, when there weren't
many files. But as I started to add more and more code, I began to
experience random problems here and there. They would come and go in
different places, or dissapear when I reran the build. Also, some host
machines were worse than others.
Now I only load a few essential binaries with NSALV, and the rest with
DUMP in timesharing. This seems to have fixed the problems. Phew.
Do you have patches for NSALV or DSKDMP? (Or to anything else in ITS?)
