i went one better, in a y2k contract i had.  i won't bore you with all
the sordid details, but i decided to roll the machines from sunos4
[various versions] to solaris 2.6 by jumpstart.  there was fortunately
an empty seat, so i used that machine to fine-tune my finish script to
install the recommended patch cluster and customize for the company's
and group's env.  when i was done, the machine came up ready to work.

the two u10s, which i reinstalled just to make them uniform, took 15m.
the five ss20s took 40m.  the lone ss2 took 2h, but it was really not
needed.  simultaneously, over lunch on a friday.  the group would have
the pm to check the changeover, and i'd have the weekend to back it
out if necessary, but it went smoothly.

not long after, i heard from my boss that one of the u10s had crashed
mysteriously, and after poking around a bit and finding nothing he
gave up and re-jumped it.  shortly after that i noticed a patch for
2.6 on u5/u10 which sounded just like the problem he'd described.
