Re: Initrd - cramfs image is not being recognized by 2.4.20 kernel

[Keith Goettert <Keith@EcologyEnergy.com>]

My support of cramfs was complied into the kernel, but it still would not work.  A very telling sign that it was compiled in was its complaint that it couldn't find a valid filesystem in the boot messages (which according to my readings is also a disputed and unresolved bug/feature.)  Now I have redone the initrd image as an uncompressed ext2 fs.  I am still not home free (many many errors that need to be checked) but it does appear to be mounting it.  STAY TUNED this is going to be a HOWTO when I'm done.  I can't believe the number of hours this has taken!

The vanilla linux kernels don't support cramfs. See mkinitrd(8):

By  default  mkinitrd  will  generate a CRAMFS image.  This is not cur-
rently supported by Linux.  However,  the  Debian  prepackaged  kernels
have been patched to support it.  You can also generate an initrd image
of another type by changing the MKIMAGE setting in mkinitrd.conf.

So long
