upgrade revision 1.1 
1Before updating, you probably would want to backup your original
2filesystems!

4The update procedure will not overwrite or remove any files not present
5in the sets you install. If you've replaced programs present in the
6distribution, you have to replace them again after you did the update.
7The etc-set needs special caution. You generally don't want to install
8this one when upgrading. It is recommended that you get a copy of this
9set and _carefully_ upgrade your configuration files by hand.
10Before starting the actual procedure, make a note of the partitions your
11root- and usr-filesystems are on. You'll need to mount them by hand.
12
13Ok, let's go. Insert the bootfloppy and follow the 'normal' installation
14procedure until it asks you if you wish to proceed with the installation.
15Now enter 'n' and hit return. You will be left at the shell prompt. Now
16mount your root and usr filesystems on /mnt. If your root-filesystem is
17on sd1a and your usr-filesystem on sd1d this would require the following
18actions:
19	mount_ffs /dev/sd1a /mnt
20	mount_ffs /dev/sd1d /mnt/usr
21
22At this point, you can follow the section "Installing the NetBSD System"
23to install the sets. There is one difference: When Extract asks you 
24	"Are you installing a -current snapshot? [n]"
25answer 'y'.

27Once you are done installing the upgrade sets, then reboot:
28	cd /
29	umount -av
30	halt
31	<reboot>
32
33Now you can boot your upgraded system as usually, but take the
34new kernel! To finish up, you should rebuild your /dev-directory:
35	cd /dev
36	MAKEDEV all
