i was sysadm at a high-end network gear co [not cisco] in the mid
'90s; we ran nothing but sunos4 and openwin for our chip-design sw and
i managed 100-200 desktops. i don't recall any stability problems
with either sunos4 or openwin. i do recall that while 4.1.4 was
released with the ross patch for multi-cpu hypersparcs, it worked just
fine with dual-proc supersparcs too [90+ day uptime on 2 different
machines under heavy chip design/sim when i left], and the clever way
i figured out to distribute patches, skeleton fs trees with just the
patch files in place. i only had to untar and move a patch into place
once, for the whole facility. i could then rdist the tree, and all
patches not already installed would be copied over in a single
command. loop the cmd through a list of machines...
i ended up with 3 trees: kernel, which i could rdist any time;
openwin, which i could do if the user logged out; and all the rest,
which had to be followed by a reboot. the only patch that ever gave
me problems was rdist itself, which caused the rdist patch process to
crash. i handled that with rcp.
it's possible unpatched openwin was unstable, but patches were freely
avaiable back then and we used them, and they were already at 4.1.3
when i got there.
anyone else ever do anything like this?
that's also the place where i came up with the sunos4 kernel tuner i
posted recently, from a sun performance overview newsletter i read
