Please notice that you should have a fast network connection as all the Debian
packages will be downloaded and installed via network. If you want to use a
local mirror (strongly recommended if you plan to use grml-live more than once)

Usage examples
--------------
-To get a Debian-stable and Grml-based Live-CD using /grml/grml-live
+To get a Debian-stable and Grml-based Live-CD using ./grml
as build and output directory just run:
# grml-live
* 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.

+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).

as well. So there we go.

Make sure apt-cacher-ng is running ('/etc/init.d/apt-cacher-ng restart').
That's it. All downloaded files will be cached in /var/cache/apt-cacher-ng then.
First of all create the chroot using debootstrap (requires root):
