Welcome to the 2.x.x -> 3.0 upgrade procedure!
|
1995-10-19 17:15:43 +01:00
|
|
|
|
|
|
|
|
It must first be said that this upgrade DOES NOT take a particularly
|
1996-11-13 13:35:17 +01:00
|
|
|
sophisticated approach to the upgrade problem, it being more a
|
|
|
|
|
question of providing what seemed "good enough" at the time. A truly
|
|
|
|
|
polished upgrade that deals properly with the broad spectrum of
|
1997-02-08 18:46:06 +01:00
|
|
|
installed 2.x.x systems would be nice to have, but until that gets
|
|
|
|
|
written what you get is this - the brute-force approach!
|

|
|
|
|
|
|
|
|
What this upgrade will attempt to do is best summarized thusly:
|
|
|
|
|
|
|
|
|
|
1. fsck and mount all file systems chosen in the label editor.
|
|
|
|
|
2. Ask for a location to preserve your /etc directory into and do so.
|
|
|
|
|
3. Extract all selected distributions on top of your existing system.
|
|
|
|
|
4. Copy certain obvious files back from the preserved /etc, leaving the
|
|
|
|
|
rest of the /etc file merge up to the user.
|
|
|
|
|
5. Drop user in a shell so that they may perform that merge before
|
|
|
|
|
rebooting into the new system.
|
|
|
|
|
|
|
|
|
|
And that's it! This "upgrade" is not going to hold your hand in all
|
|
|
|
|
major respects, it's simply provided to make one PART of the upgrade
|
|
|
|
|
easier.

|
IMPORTANT NOTE: What this upgrade procedure may also do, in fact, is
|
1995-10-19 17:15:43 +01:00
|
|
|
completely destroy your system (though much more quickly than you
|
1995-10-20 11:01:39 +01:00
|
|
|
would have been able to destroy it yourself). It is simply impossible
|
|
|
|
|
to guarantee that this procedure's crude form of upgrade automation
|
|
|
|
|
will work in all cases and if you do this upgrade without proper
|
|
|
|
|
BACKUPS for any important data then you really must like living life
|
1995-10-20 15:26:15 +01:00
|
|
|
close to the edge, that's all we can say!
|
|
|
|
|
|
|
|
|
|
NOTE to 2.0 users: We're sorry, but the "slice" changes that were
|
|
|
|
|
added in FreeBSD 2.0.5 made automated upgrades pretty difficult due to
|
|
|
|
|
the fact that a complete reinstall is pretty much called for. Things
|
1996-12-15 19:14:37 +01:00
|
|
|
may still *work* after an upgrade, but you will also no doubt receive
|
|
|
|
|
many warnings at boot time about non-aligned slices and such; we
|
|
|
|
|
really do recommend a fresh installation for 2.0 systems! (But back
|
|
|
|
|
up your user data first :-).
