Re: [ts-7000] Re: Redboot and kernel 2.6.21-ts

["Dustin Oprea" <>]

Thanks.. The information on the NFS-rooting was exactly what I needed.

As per the comment about the construction of the root filesystem, I'm more just wondering if it's as simple as just copying an existing root filesystem to the NFS root. The device don't matter, right?.. With devfs running, they should be automatically established.

I get the kernel via http, so at redboot I use:
"load -v -r -b 0x218000 -h 192.168.2.1 -m
http /~ccm/zImage-2.6.22.4-rt9"

192.168.2.1 is the server, and zImage-2.6.22.4-rt9 is one of my test
kernels in my home public html directory.

[Note: these are my development kernels, not the TS-released ones.
I haven't had a chance to try them out ...]

Once loaded, I use the following exec line:
exec -c "root=/dev/nfs nfsroot=192.168.2.1:/home/armel-root-fs
console=ttyAM0,115200 ip=192.168.2.30"

Again, 192.168.2.1 is the nfs server, and my nfs root fs is in a
separate home directory named armel-root-fs. the 192.168.2.30 is
the ip address of the ts-7250 I use.

Sorry, don't know. I guess you could, if you get the device nodes
transferred OK, etc. But why restrict yourself to a small distro?
With NFS you can use more of a full-blown system.
