Building the inotify kernel | Nick Bettison LINICKX.com

I'm in the process of tring to get beagle working on my FC3 Laptop, being my usual read the instructions later self, I added the yum repo suggested on Beaglewiki.org and it resolved all it's dependencies, and I thought all was good, but it wasn't :( .

Turns out my laptop installed the latest kernel from the official fedora updates, rather than a custom one that i needed... So I decided to have a go at building it myself :D

The beagle guys provide their own src.rpm so I just tried using the "patch" info in that to patch the latest proper kernel from Fedora/Redhat... but no joy :'( ...but then I found a cracking thread on fedoraforum.org

http://www.fedoraforum.org/forum/showthread.php?t=29434&page=1&pp=15

So this is what I did....

(1) Install the "proper" source kernel rpm kernel-2.6.10-1.770_FC3.src.rpm
(2) From the src.rpm provided by beaglewiki/Ben Konrath I extracted inotify.patch
(3) Then from my \~/rpmbuild/SPEC dir I ran

\$SHELL\>rpmbuild -bp --target=i686 kernel-2.6.spec

(4) make your custom kernel custom edit \~/rpmbuild/BUILD/kernel-2.6.10/linux-2.6.10/Makefile

EXTRAVERSION = -inotify\_linickx

(5) apply the inotify patch from \~/rpmbuild/BUILD/kernel-2.6.10/

\$SHELL\>

patch -p0 < /path/to/patch/inotify-0.19.patch

(6)Check the patch went on.... run:

\$SHELL\> make menuconfig

and check that Device Drivers -> Character Devies - Inotify is "stared"
(7) Build your kernel/rpm

\$SHELL\>time make rpm

time show how long the command took

Now that I'd built my kernel, I needed to install it...

(8) the rpm/kernel is in \~/rpmbuild/RPMS/i386, so I installed it

\$SHELL\>sudo rpm ivh kernel-2.6.10inotify\_linickx-1.i386.rpm

but for some reason this isn't enough... :( so the next step was to ...
(9)

\$SHELL\>cd /boot \$SHELL\> sudo /sbin/mkinitrd /boot/initrd-2.6.10-inotify\_linickx 2.6.10-inotify\_linickx

(10) and finally /etc/grub.conf needs some new entries... mine look like:

title Fedora Core (2.6.10-inotify\_linickx) root (hd0,2) kernel /boot/vmlinuz-2.6.10-inotify\_linickx ro root=LABEL=/ rhgb quiet initrd /boot/initrd-2.6.10-inotify\_linickx

and then I was able to reboot into my new kernel :)

Please note: If you want to use the inotify device you will also have to add a line to your /etc/udev/permissions.d/udev.permissions. You will need to add

inotify:root:root:666

to the very bottom so that it will hold its permissions on each reboot.

Hopefully now I can press on getting the beagle to work ;)
