Tomoyo looks really interesting for improving security, but the installation page says:
So:

• why is there a tomoyo 2.2 package in my repository (and not installed) if it's already included in the kernel?
• Where do I change the kernel's command line parameters?
• What if I want to use the Liquorix kernel?

I did google, but didn't find anything that helped. Any tips appreciated - thanks.

Btw, I have the 2.6.32 kernel (2.6.32-34squeeze1, whatever that means) and also the liquorix kernal installed (choice given at boot). I'm running CrunchBang, which is the same as a minimum install Debian Squeeze but with a custom Openbox desktop.

What they are referring to is that the kernel will support the package already and the package will install using the install script for dpkg.

I am running Debian testing with the Liquorix kernel. It has the standard dpkg set up. Have never had any trouble with any package from the repo.

If you do have trouble just remove the bugger. My bet is that it runs.

Not sure why anyone would want the thing. Plenty of tools for the same things already included in your install or actually part of the kernel. That is me though, it is your box and your choice. I sure don't worry about what others think of what I do on mine.

these are the user-tools, you need them to administrate the rules and domains.
in /etc/default/grub. Add it to the line GRUB_CMDLINE_LINUX_DEFAULT="security=tomoyo", then do 'update-grub'.
no idea since I don't know this kernel. Type 'cat /boot/config-whatever | grep tomoyo' to see if the kernel supports tomoyo.
