hi, i am trying to modify a geexbox install but i cant extract the initrd.gz file; heres what i tried:

Code:

[fedora@localhost fedora]$ mkdir geexbox; cd geexbox
[fedora@localhost geexbox]$ cp -r /media/GEEXBOX/* .
[fedora@localhost geexbox]$ ll
total 4536
drwxr-xr-x 3 fedora fedora    4096 2009-06-24 21:54 boot

gzip: initrd.gz: not in gzip format

[fedora@localhost geexbox]$ mkdir temp
[fedora@localhost geexbox]$ sudo /sbin/losetup /dev/loop9 initrd.gz
[fedora@localhost geexbox]$ sudo mount /dev/loop9 temp

[fedora@localhost geexbox]$ sudo mount -t cramfs /dev/loop9 temp
mount: wrong fs type, bad option, bad superblock on /dev/loop9,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so
# -t ext2 ext3 vfat sqaushfs... also doesnt work
[fedora@localhost geexbox]$ sudo mount -t ramfs  /dev/loop9 temp
[fedora@localhost geexbox]$ ll temp

[fedora@localhost geexbox]$ sudo umount temp
[fedora@localhost geexbox]$ sudo mount   initrd.gz temp -oloop,ro

[fedora@localhost geexbox]$ sudo mount -t ramfs  initrd.gz temp -oloop,ro

[fedora@localhost geexbox]$ sudo umount temp
[fedora@localhost geexbox]$ cd temp
[fedora@localhost temp]$ cpio -id < ../initrd.gz
...

[fedora@localhost geexbox]$

any ideas would be appreciated.

this is one file that has been compressed of raw data. there is nothing to extract. it is an initrd.img yes an image that has been compressed. you could rename it initrd.img and linux will treat it the same. gz format . gz format is built into the kernel so it can read the image.
good luck.
you really need to be much more clear about your goal. when asking a question.
I want to make a custom initrd.img . I want a custom kernel. I want modify my install but that has nothing to do with the kernel and it's initrd.img
good luck on installing a gnu file system to you hard drive so your linux kernel can boot it and then load the modules from the initrd.imag.
hang in there . learning curve time

i did the following and i got further:

Code:

[fedora@localhost temp]$ mv initrd.gz initrd.lzma
[fedora@localhost temp]$ unlzma initrd.lzma
[fedora@localhost temp]$ ll

-r--r--r-- 1 fedora fedora 29941760 2009-06-25 00:34 bin.tar

[fedora@localhost temp]$ file initrd
initrd: ASCII cpio archive (SVR4 with no CRC)
[fedora@localhost temp]$ mkdir initrd-extract; cd initrd-extract; cpio -id < ../initrd

thanks,

it would be nice if i can get sshfs installed on geexbox; anyone got any bright ideas how ?

open a terminal asume root type

Quote:

yum install fuse-sshfs

if you do not have yum instlled wich I could never think of a fedora with out it.
urpmi yum.

^ thanks, i actually already have it installed on my fedora machine.

i dont know what geexbox is based on (maybe knoppix/ debian); but i would like to have sshfs installed on my geexbox machine. it doesnt seem like the developers included a facility to install new stuff.

i have tried xbmc which is debian based and was able to do

Code:

sudo apt-get install ssh;sudo apt-get install sshfs

.
and all is good in the world for rite now; except that i am wondering if there is a way to automatically mount directories under $HOME rite after boot-up.

edit: put the sshfs command in the last line of .profile
