[Fedora-livecd-list] how to modify a livecd

[bill pemberton]

i would like to modify a live cd to have a root and user account and to
mount a home directory for the user.  i have taken a fedora 12 iso, broken
it apart, made my changes and need to create the bootable iso image.  that
is where i'm running into a problem.  i have tried using the grub
stage2_eltorito file but that didn't work (maybe the command i copied was
incorrect).  i have thought about snagging the first sector (i think that is
right) of a good iso and merging that with what i have but i have a feeling
that won't work.  from what i can tell i need a boot image file to use but i
have not been able to locate one of the correct size (per the mkisofs man
page) in the files i have for the iso.  the docs i have been reading today
so far haven't indicated where i can find this file and web searches haven't
been very fruitful.  since i'm not changing the packages but just the
contents of the passwd, shadow, and fstab i would think this would be an
easy thing to accomplish.  i have looked into using a persistent image but
after waiting nearly an hour for the image to be written (using
livecd-creator) i felt that that must not be working correctly either.  i
can get an sd card to boot via writing the iso using dd and so far that is
the only way to get an sd card or usb drive to boot.  so i must be missing
something with this livecd-creator (and i think the livecd-iso-to-disk
script as well).

the main idea is to have a bootable livecd on an sdcard, use a usb drive for
the home dir for a user and this way have a dual boot machine and be able to
test different distros from time to time.

would someone mind pointing me in the right direction to accomplish this
goal?
