In case anyone was thinking of doing this...
I know this isn't supported, but I thought I'd try upgrading a
throw-away 5.4 machine (which, IIRC, has been upgraded from
SL4.something) to 6.0. I had to use the boot disk since the machine
doesn't have a DVD drive. Then I had to give it the boot option
upgradeany to get it to offer an upgrade. This machine only has 512mb
of RAM (I remember when that was a lot), causing it to decline to
attempt a graphical installation and proceed with a text-based
install.
While it was starting the upgrade and it blathered a bunch of "putting
<package> in simple update" messages across and down the screen,
making for an interesting background pattern. Rather amusing in a way.
I have a screenshot of anyone wants to see it.
As for the results of my experiments in upgrading, I don't recommend it.
1. There were a bunch of SL5 packages that didn't get removed, and
apparently a couple of the SL5 packages were considered "newer" than
the corresponding SL6 packages (I later upgraded them with rpm's
--oldpackage option).
2. SELinux seemed to be rather hosed up. Attempting a relabel
generated a lot of messages about conflicting specifications, and
whenever the system booted it'd throw a lot of "operation not
supported" from setfilecon on all the /dev files. Very little would
even start with SELinux enabled.
