Using exim's filters to call bogofilter seems to be outside the realms of it's capabilities. The exim mailing list hints at it's possibilities:

And the thread that it references:

http://www.exim.org/mail-archives/exim-users/Week-of-Mon-20021118/msg00063.html

To quote it:

I recently set it up in my .forward (also wanted to stay within
exim).  It requires a small setuid (or setgid) program bogofilt to
access the exim spool directory -- see the previous thread on
'$message_filename ?'.

	if "${run{/bogofilt $message_id}{s}}" is s
	 then	unseen pipe "bogofilter -s"
		deliver spam
	 else	unseen pipe "bogofilter -h"
	 endif

bogofilt simply runs a shell script bogofilt.sh, which includes:

	cd /var/spool/exim/input &&
		{ sed '1,/^$/d; s/^[0-9][^ ]*  *//' "$1-H"
		  sed '1s/.*//; s/^From />&/' "$1-D"
		  } | bogofilter

The sed scripts rebuild the message and protect "^From " lines;
simply cat-ing the files might be sufficient.

*argh* that wasn't the least bit lame. Symptoms are the X server segfault'ing after installing the nVidia drivers. The summary link is here. It basically says to do two things:

1. Disable SELinux while installing the nvidia driver:
   

   
   # /usr/sbin/setenforce 0
   # /path/to/NVIDIA-Linux-$ARCH-$VERSION-pkg1.run
   # /usr/sbin/setenforce 1

   
   


2. Patch /etc/X11/prefdm:

All in all, it seems to be something broken after 7174 in FC4. To avoid this lameness, you could just downgrade.

Fun with initrd images. On a RedHat machine:

• cp /boot/initrd-2.6.xx-1-667.img /tmp/initrd.gz


• cd /tmp && gunzip initrd.gz


• mkdir a && cd a


• cpio -idumv < ../initrd

That'll uncompress the image. Make your changes, then:

• cd /tmp/a


• find . -type f | cpio -ocO /tmp/newinitrd.unc.img


• cd ../ && gzip -c newinitrd.unc.img > newinitrd.img


• mv newinitrd.img /boot

Continue on with your happy life.
