Is there some problem that needs the kernel to look exactly like the

Well, if I want to use the kernel modules from livna/extras, I need
the version # to be identical. Just a change in the SMP flag
shouldn't break anything right? I'm leaving the rest of the
configuration untouched.
Not sure; some of the modules might build differently with the SMP flag
set/not set. I'd be very wary of doing this. Could you not rebuild the
modules you need from the SRPMs, as you're doing with the kernel itself?
I haven't had a chance to look at the link yet but if you only
need to rebuild the modules you only need the Kernel development
package, if you need to turn on/off other features you need the
Kernel source (such as with NDISWrapper and the 4K -> 8K stack
change). One other thing to note, we're used to seeing the
kernel version (uname -r) look like this:
2.6.15-1.2-54_FC5
Well it breaks down like this:
- Version: 2
- Patch level: 6
- Sublevel: 15
- Extra version: -1.2054
- Local Version: _FC5
That info can be found in the following places:
Makefile
VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 15
#EXTRAVERSION = -prep
EXTRAVERSION = -1.2054
NAME=Sliding Snow Leopard
.config
CONFIG_LOCALVERSION="_FC5a"
I added the EXTRAVERION (was -prep) and CONFIG_LOCALVERSION (was "")
to make my kernel more compatible with upgrades. Also I don't use
a .rpmacro (sp?) file so I keep everything under /usr/src/redhat/BUILD.
Here's what I use;
1 wget
ftp://ftp.mirror.edu/pub/fedora/linux/core/updates/4/SRPMS/kernel-2.6.12-1.1390_FC5.src.rpm
2 rpm -ihv kernel-2.6.12-1.1390_FC5.src.rpm
3 cd /usr/src/redhat/SPECS/
4 rpmbuild -bp --target=i686 kernel-2.6.spec
5 cd ../BUILD/kernel-2.6.12/linux-2.6.12/
6 cp configs/kernel-2.6.12-i586.config config.bak
7 cat config.bak | sed -e 's/CONFIG_LOCALVERSION=""/
CONFIG_LOCALVERSION="_FC5"/' | sed -e 's/\(CONFIG_4KSTACKS\).*/# \1 is
not set/' > .config
8 cp Makefile Makefile.bak
9 sed -e 's/^EXTRAVERSION = - prep.*/EXTRAVERSION = -1.1390/' <
Makefile.bak >Makefile
10 make oldconfig
11 make rpm
12 cd /usr/src/redhat/RPMS/i386/
13 rpm -ivh kernel-2.6.12prep-1.i386.rpm
14 cd /boot
15 mkinitrd initrd-2.6.12-1.1390_FC5.img 2.6.12-1.1390_FC5
16 cd grub/
Note that you can replace #6 with:
cp configs/kernel-2.6.12-i586.config .config
and #7 can be removed. I don't know how useful this information is
but I'm using it in a book.
