Re: LNX-BBC-NET (bbc 2.1 hacked into a netboot) - network rescue floppy

Thank you -- I'll probably follow up on this mailing list w/an updated
version with all future lnx-bbc releases .. Sorry about not using the
cloop, it's just that this release begs to become a simple starting
platform for other things and requires being updated with greater ease.
(not to you exactly per se..) So for the time being the network boot
method is for machines with a good chunk of memory in present standing.
Memory is cheap.

The pain in the ass is making the initial ramdisk.

#1: Gauging your ramdisk size based on whatever machine you currently
have booted.. df.. your root device should use a little under whatever you
are going to set the ramdisk size to minus your space for customization.

#2: If you wanted to say make a 128 M ram disk (1024*128)..
   AA) You would need two machines.. one to boot into the environment,
       and another to make the image on and to copy the files into.
    1) You have to boot your kernel with ramdisk_size=131072
    2) You mke2fs -m 0 /dev/ram0 on bootup, then
    3) mount /dev/ram0 /mnt
    4) rsync all the files ( excluding /proc,/dev ) from your booted host
       to this machine
    5) mkdir -p /mnt/proc /mnt/dev
    6) umount /mnt
    7) dd if=/dev/ram0 of=root
    8) gzip -9 root   ( takes awhile )
