I guess it's better to have them aboard that not :) Another issue with
sysinst is when user wants to install sets from unmounted fs; installer by
default doesn't use -G flag when it mounts filesystem. To make it work
filesystem field must specified like "msdos -o -G" or filesystem should
be mounted before extraction of sets starts and "local filesystem" method
should be used; at least this must be documented.

Whatever we do, maybe we should keep one kernel without RELOC_KERNEL
because there's comment in atari/atari_init.c in line 151 saying that
RELOC_KERNEL does not work on all TT's.
