do you man disable or enable initrd support??
- at least its black-n-white, in that we supposedly
know what to do with that option
but what about other options like, ramdisk support too which is
NOT the same as initrd support
or do you only want to use loop devices ?? and why use loop devices, etc
..
gazillion examples ...
- in each distro .. there typically is an initrd.gz or similarly
named files somewhere on their boot media
http://Linux-Boot.net/InitRD/Viewing/
to break those initrd.gz so you can peek isnide would depend on how
they built it ... and sometimes its compressed and sometimes not
even if its named to imply one way or the other
( *.img vs *.gz vs *.foo )
- some use minix + cramfs ... which your system would need
to support for you to peek in
for making your own ...
look at the contents of other distro's initrd, since we all
know the distro's CAN install into most any hardware
after reading/studyng their stuff, you can make your own with:
http://Linux-Boot.net/InitRD
- ramdisk
- loop devices
ramdisk is limited in size by the kernel option at kernel compile
time ...
dd if=/dev/zero of=/dev/ram0 bs=anything count=big
will NOT work
loopdevices can be any size
