When used in disk mode, GNAP uses the syslinux.cfg file (in
specs/isolinux) to pass boot options. The core file includes that file.
Then the gnap_overlay script takes that file from the core, rewrites it
with some options, and then syslinuxes the disk.
Look for :
sed -i "s:cdroot:cdroot=/dev/${TARGETROOT} ${CACHE}${SERIAL}:"
"${TEMPMOUNTDIR}/syslinux.cfg"
in gnap_overlay
So you can either add your parameter to the syslinux.cfg file in the
specs and rebuild your core, hack the syslinux.cfg file from the core
tarfile directly, or hack the gnap_overlay script to do your bidding.
Something like
sed -i "s:cdroot:reboot=bios cdroot=/dev/${TARGETROOT}
${CACHE}${SERIAL}:" "${TEMPMOUNTDIR}/syslinux.cfg"
should do the trick.
Hope this helps.
