Hello all,
Just trying out udpcast, using PXE after having recompiled the kernel to
support a serial console (headless machines).
This is what I get :
RAMDISK: Couldn't find valid RAM disk image starting at 0.
Kernel panic: VFS: Unable to mount root fs on unknown-block(1,0)
It seems that the initrd is wrong (downloaded at
http://udpcast.linux.lu/20060326/initrd).
# file initrd
initrd: data
It's not in bzip2 format, it's not cpio either.. so am I doing something
really wrong or is the file corrupted ?
# md5sum initrd
80867761052b76e14d69f95fa9b0c8ba initrd
best regards,

Make sure to include LZMA support into the kernel (patch is on udpcast site)

It's not corrupted, it's just compressed using lzma rather than bzip2

Right, that was the problem.. was fooled by "file" which didn't know that
format, sorry !
Now, I've recompiled a kernel with the necessary options to get a serial
console, but I loose output after udpc_dialog starts. So I'm trying to
modify the inittab in initrd to start ash instead and see what's wrong.
Unfortunately I'm failing to build an initrd the kernel will recognize
(unpacked the original, modified it, cpio, lzma e ...)
Seems I need initramfs-tools but in turns this requires a newer udev on
debian stable....
Any easier way ? I've tried a cramFS image with no luck.
Cheers,

(ROMFS was used for 2.4 kernels, but is now considered obsolete)
