Hi all... Trying to setup an LFS system to boot off a usb flashdisk, for use in setting up on new hardware. Not a problem, other than one thing - working out what device the rootfs should be on. Currently it's configured in syslinux to use /dev/sda1, but I'd prefer something a little more flexible given it's supposed to work on different hardware.
What I *could* do is something like the following command:
grep -l 'RunDisk' /sys/block/*/device/model |
( IFS=/ read -a foo; echo ${foo[3]} )
or some variant thereof. But I've no idea where it should be run from -
I understand an initramfs is the appropriate mechanism for running stuff
at this stage of bootup, but I don't know how to set one up. Can anyone
offer any pointers?
Simon.
