My advise:

Perhaps xpostfacto 2.2.1 is better than 2.2.4 for 10.2, at least on my 
7500/G3. Have enough space on your HD (3-4gb). Avoid updating from previous 
versions of OS X if you can. If you must update, be certain to select the 
"install additional applications" in the installer, or be prepared to have 
bad results. Install the 9-20-02 Security Update before updating. Use 
Software Update to install 10.2.1, Installer is bad.


My experience:

I've just completed two installs of 10.2. The first was using xpostfacto 
2.2.1 and was a clean install on a fresh HD. It went flawlessly, about an 
hour, with no need to unhook external SCSI or rearrange dimm, etc. A joy.

The second was an upgrade of 10.1.5 on the same computer but different drive 
using xpostfacto 2.2.4. (2.2.2 & 2.2.3 had caused panic and wouldn't work). 
The first thing I noticed was that 2.2.4 booted in verbose mode even though 
it was not selected. Next, the installation seemed much longer, but I thought 
this was due to the limited space on the HD. Because of the limited space, I 
deselected the install "additional applications" which was a single large 
package with no individual selection options. When it finished, several files 
generated "security warning" errors and gave me the choice: disable, use, or 
fix & use. I chose fix & use, although I had little idea of what the files 
did or whether this was the correct choice. Then I went to upgrade to 10.2.1 
using the download instead of Software Update. The Installer when through the 
legal and drive selection fine, but stalled hard at the "Install" button. I 
found an Apple knowledge base article that mentions this behavior, and 
recommends using the "stand alone" installer, but a search yielded nothing, 
and I assuimed I was already using the "stand alone" Installer as opposed to 
Software Update. During the search, I found a second article that said 
upgrades with the "additional applications" deselected (not installed) will 
corrupt many installed applications, and mentions how Acrobat Reader will be 
converted to a folder that won't launch. Sure enough, my Reader was dead 
folder, and several app's icons and folders disappeared completely (Explorer 
was one). I don't know OS X stuff, but everything was crawling slow, and I 
thought the L2 cache was disabled. I had L2cacheconfig. in my startup items 
of 10.1.5, but it appeared not to work in 10.2. I decided to install the 
Powerlogix Cache Control using their Terminal install instructions (they say 
the Apple Installer is buggy). When I went to Terminal, it wouldn't install. 
It was in tcsh instead of sh? (I don't know this shell stuff, it said tcsh 
and wouldn't install). I decided the upgrade was screwy and had gone bad. 
Thus, I was "forced" to reinstall the upgrade over itself, this time leaving 
the "additional applications" to be installed. On the small 1.5gb partition, 
this took forever. On the first upgrade, there was no time remaining function 
to see, just the progress bar. This time, it said 1 hour 37 minutes to start. 
then went up some, but within 30 minutes appeared 90% finished, and said 2 
minutes left. When it got to "less than 1 minute" I looked at my watch and 
thought, "this is quick." 37 minutes later it finished! It said less than 1 
minute for 37 minutes! Then came the optimization. 1% at a time, very, very 
slow. It took probably 2 1/2 hours total? This time, no "security" problems 
with files (but perhaps this was because I chose "fix & use" the first time.) 
I go to 10.2.1 installer and it stalls again at the same place. I'm so 
frustrated I go to software update, and see that a 9-20-02 Security update. 
It might have been the problem? At least it finally works, and 10.2.1 is 
installed. I hit Terminal and see it's in sh, and install the Powerlogix 
Cache Control (after removing all the remaining L2cacheconfig. files) and it 
works. Up and running at speed. Total time around 6 hours, very frustrating.
