The easiest way is to do a make "oldconfig".  That will load all of your old

Forgive me for not yet being a kernel expert. Before I do this what exactly does "make oldconfig" do?


It configures the kernel source tree with the kernel configuration
settings from file ".config" in kernel root directory. The interactive
alternative is to run "make menuconfig" (or "make xconfig").


Where does it get the config file from?


File ".config", e.g. /usr/src/linux-2.4/.config


Does it grab the config file that matches the running kernel?


No. That is a manual step.

cp /boot/config-$(uname -r) /usr/src/linux-2.4/.config


FYI:

I tried make oldconfig and it looked in and took it's info from /usr/src/linux-2.4/config/kernel-2.4.20-i686.config, which is what I get with uname -r. Then it created a new ".config" file from that so copying the config file was not necessary.

And I finally found the ACL patch for ext3 at: http://acl.bestbits.at

Does Redhat have an official supported ACL patch?
