Does apt work with Red Hat in a usable way? I tried it a long time ago,
and deleted it.

I have used rpmfind --autoupgrade
to upgrade from 7.1 to 7.2, and that required not a huge amount of manual
intervention, but more than I want.
I tried using rpmfind to upgrade this machine from 7.2 to 7.2.93, but it
changed my /lib/ld-linux.so and everything ground to a halt.
I had to reboot with init=/sbin/sash to fix it. Now I have created a
/static, containing lots of statically compiled tools, including the LVM
We really need a rescue disk that supports LVM, RAID, reiserfs and ext3.
Anyone seen such a beast, or do I have to make it myself?

So you are not yet running a recent kernel?
