Yes. So Unix did have a shutdown procedure, and it was particularly critical to do it and
do it right. I remember when I first heard about Unix, when at the U of Illinois -- some
PDP11s in the Center for Advanced Computation ran it, for their Arpanet connection. The
story was that CAC was a good facility to run Unix because it had very reliable power --
it was built to house Illiac 4 before that machine was moved to a military facility in
response to campus protests. So there was little worry about having to repair the file
system manually after a power failure -- I guess fsck hadn't been created yet, or
perhaps wasn't reliable yet.
