Hi folks,
We are trying to create a Fedora Core 5 customized distro.
But, when we added a package called kernel-module-ntfs
anaconda broke because it couldn't solve the dependencies.
I looked for it and found that it was happening because
the function handleKernelModule was missing.
This function was in depsolve.py, in early versions, but this
file was removed from the anaconda-11.1.0.4.
At some point in yuminstall.py we have some functions
taken from depsolve.py, but handleKernelModule wasn't
there. I fix the problem adding the function in
yuminstall.py with the other functions from depsolve.py.
I hope I have helped.
Best regards
Andre

Well, at this point kernel module support isn't supposed to be in Yum
propper. Current CVS of anaconda shows that call commented out (line
562). And that's the correct answer here, anaconda should not be
calling that function. In fact, Jeremy, see attached.

All of the depsolving stuff in anaconda needs to be cleaned up as the
changes for CD support are pushed down into yum proper (which Paul is
working on)

With what may be a new job and RHEL 5 looking like it will be completely
Yum based I'll have a lot more time/ability to sit down and work on that
plugin so it doesn't suck.

Jeremy, how are you planning to handle Yum plugins in Anaconda?

Haven't decided yet ;) Realistically, we'll probably need to end up
using the "base" set of yum plugins we ship in Core by default and then
possibly some kickstart syntactic sugar for people who want to go crazy
and add additional plugins there. But they could really already go
crazy in %pre.
