My dump/restore parameters
 --> # dump 0cebBf 10 4096000 /dev/rmt0
                   # under 1.5.2; Tape: TLZ06 (2/4GB), 90m tape cartridge

 --> # restore -r -b 10 -s 1 -f /dev/st0
                   # under 1.6 installation kernel

I think this 2048-byte limit is caused by the (installation) shell.
Is there are chance, to get some kind of a "rescue" system? (without having
to abuse this (sparse) installation system for survival)?

I suspect sysinst doesn't deal with ccd on upgrade as well, it doesn't
configure them. If no system partitions are on the ccd, then it's possible
to remove them from fstab for the upgrade.
Otherwise, the solution is probably to exist sysinst, configure the ccd
(hopefully the INSTALL kernel supports it, and ccdconfig is on the install
media) and restat sysinst.

What options did you use for dump ?
restore -b 10 will probably work ...
