I have somewhat higher expectations.
I have an expectation that after a few seconds (and perhaps a few
mumbled superstitious 'sync' invocations), everything that I changed
will still be there after reboot.
I have an expectation that if the system crashes at any time while I am
in the middle of applying a series of correct changes to files in the
correct order using tools that update files atomically, the system will
be able to boot back to multiuser mode and will come back with a prefix
of those changes active and a possibly longer prefix of those changes
visible in the filesystem.
I do not like sitting there in fear of a power failure during the large
chunk of a minute that "bootadm update-archive" takes to run to
completion on an X4600. (when I timed it, it took 26.5 seconds, but it
felt like several minutes).
I realize that newboot on x86 shipped before it was complete -- there
were compelling reasons why it was significantly better than what it
replaced in certain dimensions. But as best as I can tell, this is not
the case on sparc.
