Re: cramfs for root filesystem?

[Steven Hein <ssh@sgi.com>]

Sorry...  I haven't been living in the development PPC world lately.
These patches should apply against the stock 2.4.18 kernel.
Anyone is welcome to adapt them to the PPC development stuff
and the sourceforge version of mkcramfs   :)

(I'm on a new project involving an ARM processor now, so I'm not
particularly current with the PPC stuff!)
