Reiser4 installation & kernel patching

Reiser4 installation & kernel patching

Hello !

I just downloaded the 2.5.72 kernel sources and applied the -mm1 patch, now I'd want to include Reiser4 in my kernel. I tried to compile the reiserprogs sources from the bk repositery, but autoconf and then ./configure failed.
I don't really know how to patch the kernel though ... do I simply have to copy the reiser4 folder in the kernel's /fs folder, and then apply the linux-[...].patch ? This one does not work on my kernel, and I don't know if it's the right way to go.
I'd just like you to make a little howto to merge reiser4 into an existing kernel (I don't want to download the whole Reiser4 kernel tree ...) and then correctly compile the reiser4progs.

Thank you in advance,
Fred

PS : What are the lilo and grub patches in the reiserprogs source tree for ? Do they bring boot support for reiser4 partitions, so that grub for instance will be able to fetch its menu.lst file from a reiser4 partition ?

regarding reiser4progs - they are supposed to be used from snapshots for now
from from packages in the future with ready-to-use configure script, not from bk 
repository where you need to make it by you yourself and need some last 
autoconf version for that. Probably you will prefere to get some snapshot from 
http://thebsh.namesys.com/snapshots. And you will need libaal installed before
reiser4progs compiling.

No they are reiser3 related. Have a look into mentioned snapshot directory
on our web server for reiser4 patches.

Thank you for your answers ;)

Now I'd like to know how I could just patch my 2.5.72-mm1 kernel, do you
plan to release kernel patch snapshot as you do for reiserprogs ?
I just tried to install libaal & reiserprogs from the latest snapshot, and
reiserprogs ./configure stops after libaal detection without any error
message else than "libaal vx.xx detection ... no". There should be an error
message or something, and the library has been compiled and installed
though. Hopefully this will be fixed in the upcomming snapshots ;).

How far are you from achieving the Darpa-related features, so that you could
launch the first beta-test ? I just saw on your website "Reiser4 is due June
30, 2003!" : you're not serious, Hans told me a few weeks ago the
beta-testing process should take about two month from the first beta if
everything's working well, and the first beta is still to come ...
Another thing : you should update you're website "download" section, so that
the reiser4 progs links point to the official snapshots url.

Yes, we are going to release a such soon, for now you can find in that 
snapshot directory some for a bit older kernels.

it means that needed libaal version has not been detected - 'no' - likely 
because you fogot to run ldconfig after libaal installation.

It is difficult to say.

That would be great ...
Does the reiser team often modifies the kernel tree (other than the reiser4
code, off course), so that it would be possible to release a patch against
the latest 2.5 kernel ? We'd then just have to download a reiser4-kernel
daily snapshot that we would include in the kernel source tree, and then
just configure & compile the whole stuff. And maybe bk could automate both
process : making a daily (or nightly :D) kernel patch and reiser kernel
package, this will be the way for users and administrators to test your
software without having to handle with bk ;)

Now it's all right ... but you'll hopefully have to change it again soon, if
these daily snapshots are made available ;)

I'd be quite keen to try version 4 with the latest kernel release.
