upgrade revision 1.3 
1Before updating, you probably would want to backup your original
2filesystems!
3
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.
10
11    1. Starting the upgrade
12    =======================
13	Ok, let's go. Insert the bootfloppy and follow the 'normal'
14	installation procedure until it asks you if you wish to install or
15	upgrade. At this time, select upgrade.
16	You will now be greeted and reminded of the fact that this is a
17	potential dangerous procedure and that you should not upgrade the
18	etc-set.
19
20    2. Selecting your root disk
21    ===========================
22	When you decide to proceed, you will be prompted to enter
23	your root disk. After you've done this, it will be checked
24	automatically to make sure that the filesystem is in a sane
25	state before making any modifications. After this is done,
26	you will be asked if you want to configure your network. You
27	can skip this section on NetBSD/Atari for now.
28
29    3. Editing the fstab
30    ====================
31	You are now allowed to edit your fstab. Normally you don't have
32	to. Note that the upgrade-kit uses it's own copy of the fstab.
33	Whatever you do here *won't* affect your actual fstab.
34	After you are satisfied with your fstab, the upgrade-kit will check
35	all filesystems mentioned in it. When they're ok, they will be
36	mounted.
37
38    4. The actual upgrade
39    =====================
40	You will now be asked if your sets are stored on a normally
41	mounted filesystem. You should answer 'y' to this question if
42	you have the sets stored on a filesystem that was present in
43	the fstab. The actions you should take for the set extraction
44	are pretty logical (I think). You might want to read the notes
45	in section 9 (Installing the distribution sets) of the
46	installation section.
47
48    5. Finishing up
49    ===============
50	After you have extracted the sets, the upgrade kit will proceed
51	with setting the timezone and installing the kernel and bootcode.
52	This is all exactly the same as described in the installation
53	section.
