Even after running `rkhunter--propupd` the nightly run of rkhunter results in: The command '/usr/sbin/rkhunter' has been replaced and is not a script: /usr/sbin/rkhunter: POSIX shell script, ASCII text executable, with very long lines This is from a change in the output of file and looks to be fixed upstream with: http://rkhunter.cvs.sourceforge.net/viewvc/rkhunter/rkhunter/files/rkhunter?r1=1.396&r2=1.397
should be fixed in current versions in the tree then
