Code snippet from ssh_get_info.nasl which handles Slackware.

########################################################################
From the code it is inferred that executing a command 'cat
/etc/slackware-version' confirms Slackware has been installed and then only
proceed further. So if you have the permission to edit this plugin as below.
But remember this will break the chain of detecting Slackware and enforcing
the local checks in Slackware. If you run this script any other system it
sets the kb item for Slackware since we dont any checks to say which Os is
running.

# hard code Slackware release version here
buf = 10.0; # whatever version that has been installed
