1) Decide what partition layout & sizes you want (du, df, mount, etc...) http://www.openbsd.org/faq/faq4.html#Partitioning 2) Install 5.7's ramdisk kernel as /bsd.rd.57 3) on another box (BSD, Mac, Linux, Solaris, whatever...), setup inbound ssh key access for operator, & an operator writable cache large enough to hold disk dumps. e.g: /var/cache/puffy chflags nodump /var/cache/puffy 4) Shut down (practically) *everything*, leaving just init, gettys (& maybe sshd) running. 5) unmount everything possible, not /, nor /var 6) dump(8) what you want to save over ssh to another machine, e.g: [operator@puffy:~]$ dump -0anu -f - -h 0 /dev/rwd0f | gzip | \ ssh operator@another-box dd of=/var/cache/puffy/_home.dump.gz 7) TEST your dumps are restore(8) able, preferably on an OpenBSD box. Maybe there's space in /tmp for testing on the original box. 8) Reboot & boot /bsd.rd.57 9) *INSTALL* 5.7 with the manual partition layout you chose in (1) 10) Restore your dumps. 11) Get used to 5.7 & adapt your stuff to suit. 12) Celebrate by rock climbing/loch rowing/Highland Games hill running.. -- Innovation is hard to schedule. -- Dan Fylstra
