Figured out why reading the script ...
Not really to take raid devices into account ...

after studing linuxrc and mount_cdrom, I see why, while Iwas booting
from an embedded CF card, the system swap to bootcd.iso which is on
first partition of first ide disc ... but the fact ls -als
/shm/var/adm/boot/ gives empty directory listing seems a bug from
elwhere! trying to re-build the full system with i586/i586 arch (was
c3_2/i686)
strangly glibc 2.3 refuses to compile when it's about timezones ???
trying to install a fresh new lfssystem ...

as the whole system is mounted from the iso on this media ...

the more I see boot scripts, the more I'm convinced; can anyone confirme
 where/why this support has been left aside ?

Any hints to try to improve this ?
