Hi Alex.

Well, at that time I used this way to build LFS natively on reiser4, not 
virtualizing or whatever else; I added support for Reiser4 in the 
host-system and formatted lfs-partition to reiser4. Then started 
building there and everything worked; then just to be sure, since I had 
some extra unused space on disk, I booted lfs-reiser4 with its own grub 
(compiled with CFLAGS set to "-00") created the reiser4 partition from 
there and installed a new lfs all (host and new lfs) on reiser4 and 
everything worked without errors.
