Hi, Manuel!

Another problem are ccd devices and upgrade: Obviously it seems not to be
enough to change the rz- to sd-devices within /etc/ccd.conf.  What else has
to be done.

I had a few more (additional) problems during upgrade and finally I ended up
in an installation of the 1.6 from scratch.

Before the upgrade I was able to do "dump"s of "/" and "/usr";, but when I
decided to "restore" the "/"-dump (from within the installation environment)
I got the error message (from "restore"):
   st0: 10240-byte tape record too big for 2048-byte user buffer
What can I do to restore this dump-backup?

Regards. / Hilmar.

No, but when you upgrade it'll mount the root partition and parse the
fstab it finds here.

OK, so I know what's happening: sysinst is parsing your 1.5.x fstab,
which contains rz* devices. But the only disks it knows about are sd*
(because now the system probes disks as sd not rz), and it doens't
handle this case.
As a workaround, you can edit your fstab to change rz to sd before rebooting
on cd.

Either nobody did test upgrade on pmax, or he did the fstab hack.
