Re: Upgrading from 10.0 to 10.1

[Greg Troxel <gdt%lexort.com@localhost>]

I use pkgsrc/sysutils/etcmanage, which has scripts to do what Brad and
others describe, as well as automatic updating of the contents of
{,x}etc.tgz when safe.  By safe, I mean that if a file in etc has the
same hash as a file that was placed there automatically, then if there
is a new version in the incoming set, it is replaced, and otherwise it
is not.

I update along stable branches all the time (well, every 1 or 2 months),
on many machines (some domUs), and have had near zero trouble.  I don't
even reboot after unpacking the kernel, believing that there are ~never
ABI additions needed by core tools within a stable branch.   For jumping
from 10 to 11, I would definitely reboot.

As for packages, I have seen someone run NetBSD 5 packages with a 9
kernel/userland, just fine.  What you can't do is a partial upgrade of
packages, because then you get things linked with each other than want
to link different base versions.   So definitely upgrade kernel/user,
reboot, and then "pkgin upgrade" to a set that is ok, or
"pkg_admin set rebuild=yes \*" and then "pkg_rolling-replae -uvk".
