I successfully booted to the ram with my customized squash filesystem
My requirement was different. I need to always boot to the ram with the
customized filesystem so i just added this.
Based on hardy : Script casper :
You need to add <Line to add> under the follwing lines <snip>.
<snip> Find in casper
if [ ! -z "${NETBOOT}" ]; then
if do_netmount ; then
livefs_root="${mountpoint}"
else
panic "Unable to find a live file system on the network"
fi
fi
<snip>
<Line to add>
mkdir /myfs
mount -t tmpfs -o size=2G none /myfs
mkdir /myfs/casper
cp /scripts/filesystem.squashfs /store/casper/ # just hardcoded in
initrd add this and regenerate
mount -o bind /myfs /cdrom
livefs_root=/cdrom # just tell that the filesystem is under cdrom
<line to add>
You can remove the scanning of devices which will take extra time.
