Does anyone know how I can build a debian /dev tree on a RHEL 4
distribution?
This /dev tree is intended to be loaded on an embedded system that has
Debian (version 2.4.16).
I am building a debian linux system on RedHat (RHEL 4) and loading it on the
embedded box.
For RedHat, I am aware that udev will dynamically detect hardware and build
the /dev tree.
This won't work for me, because I need additional devices created.
I need to simulate the /dev tree that will be used on the target Debian box.
I have done this on a debian distribution before (that was simple, because
it already had the
debian devices tree).
For instance Redhat does not have:
/dev/hda
/dev/hda1
/dev/hda2
....
This is what I have tried so far:
I made /dev1/dev to simulate /dev and created devices under there.
But, now I this command fails:
dd if=/dev/zero of=/dev1/dev/ram1 bs=1024 count=93750
Error:
dd: writing `/dev1/dev/ram1': No space left on device
16385+0 records in

6406144 182281 6223863 3% /
Is it because of dev1's filesystem, or where it is mounted?
I made a /dev1/dev and created a devices tree that looks exactly the same as
what is on debian (the one that works).
Will that work? The dd command failed, so there must be something I am
missing or doing wrong.
I would appreciate any help!
If you think this needs to be posted to a different forum, let me know.
