I quickly found that it gives false positives on Fedora15 too.

It thinks one is infected with Suckit.

It's check is essentially "strings /sbin/init | egrep HOME" which
triggers with:

	XDG_CONFIG_HOME
	XDG_DATA_HOME
	HOME=%s

I'm sure chkrootkit might be useful as a guide, but the seeming
pervasiveness of it's false positives make it much less useful than it
could be.
