[coLinux-users] cannot install debian from iso

[Wolfram W. <Wol...@ek...>]

Hello,

trying to install debian etch rc2 businesscard image as described in the =

"colinx: Install debian From Iso" every attempt failed.

I've extracted initrd.gz from iso iamge and unpacked to initrd.
My colinux.xml look like:
(...)
     <block_device index=3D"3" path=3D"\DosDevices\i:\initrd" enabled=3D"=
true" />
     <bootparams>root=3D/dev/cobd3</bootparams>
     <initrd path=3D"initrd.gz" />
     <image path=3D"vmlinux" />
(...)

Every time starting the colinux-daemon i get the error that /dev/codb3=20
cannot be mounted.

What's going wrong?

Double check, that you have no typofixies in the config.  cobd and codb 
are not the same.
Double check that, the file exists. Try a "DIR I:\initrd" on same 
windows prompt, you starts coLinux.
Do not run coLinux in a CygWin shell.  Use simple CMD.EXE.
Check, that I:\INITRD is readable file and not on a network.  Copy it to 
other dir, for sample under C:\TEMP and use it as C:\TEMP\initrd.

Testings under a Linux:
Copy the file i:\initrd into a Linux, and try to mount it as loop:
   mount -o loop,ro initrd /mnt
Check the filesystem of the file initrd:
   fsck -f initrd

Some distries does ship initrd.gz not as compressed image file. They use 
a CPIO archicves.  CPIO can not use as cobd.  You need to transform it 
into an image file (create an empty image with dd if=/dev/zero of=image 
..., mkfs ..., mount -o loop ..., unpack the cpio archive into the 
mounted image).

Last:
Use an newer coLinux 0.8.0 and run it with option "-v 3".

What does losetup do? If that non mount it, you can not check it with 
fsck. View what are currently mountet after losetup.  But better, you 
does my steps.  Think, losetup use a ramdisk, not an initrd file.

Perhaps do "modprobe loop" before "mount -o loop,ro initrd /mnt"

Try this before you mounts it:
This should say, that is a filesystem Minix, or ext2.
"LANG=C file initrd"
   initrd: Minix filesystem, 30 char names

losetup just connects the file to the loop device without assigning a
mountpoint. You need that if you have additional parameters for the loop
device that mount does not now.

And fsck doesn't work on mounted filesystems.

What he did will work, but he should try mount /dev/loop0 to find what
filesystem is on initrd.

I did it, but Knoppix 5.2 could not mount the image nor did it respond wi=
th=20
any helpful hint what type of image the initrd from the debian testing=20
businesscard image is.

Now i'm trying the colinux 0.8.0 with a prebuild root file system image.
