* DEBORPHAN: get rid of all packages listed in output of deborphan
+* FILE_RC: instead of using systemd as init system use file-rc instead. file-rc
+was the init system used by Grml until and including stable release 2014.11,
+starting with beginning of 2016 Grml switched to systemd instead. If you want to
+build a live system in the old style using file-rc instead of systemd then enable
+this class. Please notice that support for file-rc is no longer being actively
+maintained (the Grml team happily accepts patches though) and file-rc (upstream
+wise) might disappear too.

* FRESHCLAM: execute freshclam (if it's present) to update clamav definitions
(increases resulting ISO size ~70MB). By default it's skipped to avoid bigger
ISO size.
* GRMLBASE: the main class responsible for getting a minimal subset of what's
defining a Grml system. Important parts of the buildprocess are specified in
this class as well, so unless you have a really good reason you should always
-use this class.
+use this class. Please be aware that using *just* the GRMLBASE class won't be
+enough, because the kernel packages (e.g. linux-image-i386-grml +
+linux-image-amd64-grml) are chosen in further GRML_* classes (to provide maximum
+flexibility with kernel selection). If you don't want to use the existing
+GRML_FULL or GRML_SMALL classes, define your own CLASS file choosing the kernel
+package you want to use (and don't forget to include your CLASS in the arguments
+of grml-live's -c... command line option).
* GRML_FULL: full featured Grml, also known as the "normal", full grml as
introduced in December 2011 (~460MB ISO size).
