====== NetBSD upgrade procedure (aka NUP) ======

===== Simplified procedure =====
  - Get binary sets
  - Unpack Kernel
  - Reboot
  - Binary sets
  - Postinstall check
  - Postinstall fix
  - Reboot
  - Upgrade packages as needed.

===== Extended procedure =====
I take it that you have /path/to/sets set to /INSTALL
  * If not set already, set -o braceexpand
  * Fetch binary sets from a [[http://www.netbsd.org/mirrors/|NetBSD Mirror]]. I use the DK mirror.
  * ''echo "mget *gz" | ftp -Va ftp://ftp.dk.netbsd.org/pub/NetBSD/NetBSD-5.1.2/i386/binary/sets''
  * Unpack modules 
  * ''progress -z -f /INSTALL/modules.tgz pax -rpe''
  * Unpack Kernel 
  * ''progress -z -f /INSTALL/kern-GENERIC.tgz pax -rpe''
  * Reboot server to let new kernel take effect, remember to set braceexpand if you haven't stuffed it in a login script already.
  * Unpack base, comp, games, man, misc, tests and text binary sets.
  * ''for file in INSTALL/{b,c,g,ma,mi,t,x}*tgz ; do progress -zf $file pax -rpe ; done''
  * Check etc.tgz via postinstall
  * ''postinstall -s /INSTALL/etc.tgz check''
  * And then fix via postinstall
  * ''postinstall -s /INSTALL/etc.tgz fix''
  * reboot
  * ... Enjoy new and upgraded server..
