Title: Initrd.bin File
Post by: bam on July 26, 2006, 03:51:51 am

How can one extract the files from this? Tried mounting it as a cramfs or sqaushfs, no-joy. Any other ideas?

Dear bam,

(using koen's way of saying it) lardman and adf is bullshit.
initrd.bin is similar to initrd.img used in normal linux boot.
It is a gzipped image. To mount it, first gunzip, plus
kernel have to have initrd support, then use this command

mount -t ext2 -o loop initrd /mnt

to mount it.

br,

felix.

I wouldn't, you just appear to be rude (even more so as you're not actually right).

No initrd.bin I've ever seen for a Zaurus uses ext2, they are always compressed, which means a choice of ro cramfs or rw jffs2.

Assuming it's not cramfs, best to try jffs2.

The best way to check it is to use 'file', however:

Code: [Select]

angstrom@serenity:~/website/unstable/images/20060725/c7x0$ file *

zImage-2.6.16-c7x0-20060725122119.bin:                      data
note how it differs from:

the zImage and roofts.img both have the sharp-sl header prepended, so file doesn't recognize them. That header could also explain why it won't mount/uncompress/etc

I have been able to mount jffs2 filesystems from pdaX certainly, and also the Sharp cramfs offerings.
