New Revision: 55

Modified:
   buildrom-devel/skeleton/bin/boot.functions
Log:

Make lab.conf parsing a bit smarter so that 2 modules can be passed to kexec.
This allows Xen booting, for instance with an lab.conf file like this:

CMDLINE="com1=115200,8n1 cdb=com1"
INITRD=""
KERNEL="/xen-3.1.0.gz"
MODULE1="/vmlinuz-2.6.18-xen root=/dev/md1 ro console=tty0 console=ttyS0,115200"
MODULE2="/initrd.img-2.6.18-xen"
VT="1"

Of course a simple lab.conf file with kernel and initrd still works:

CMDLINE="root=/dev/md1 ro console=tty0 console=ttyS0,115200"
KERNEL="/vmlinuz-2.6.22-14-generic"
INITRD="/initrd.img-2.6.22-14-generic"
VT="1"
