=head1 NAME
OpenSLX::ConfigFolder - implements configuration folder related functionality
for OpenSLX.
=head1 DESCRIPTION
This module exports functions that create configuration folders for specific
system, which will be used by the slxconfig-demuxer when building an initramfs
for each system.
=cut
use OpenSLX::Basics;
use OpenSLX::Utils;
=head1 PUBLIC FUNCTIONS
=over
=item B<createConfigFolderForDefaultSystem()>
Creates the configuration folder for the default system.
The resulting folder will be named C<default> and will be created
in the I<OpenSLX-private-path>C</config>-folder (usually
C</var/opt/openslx/config>).
Within that folder, two subfolders, C<initramfs> and C<rootfs> will be created.
In the C<initramfs>-subfolder, two files will be created: C<preinit.local>
and C<postinit.local>, who are empty stub-scripts meant to be edited by the
OpenSLX admin.
The functions returns 1 if any folder or file had to be created and 0 if all the
required folders & files already existed.

}
=item B<createConfigFolderForSystem($systemName)>
Creates the configuration folder for the system whose name has been given in
I<$systemName>.
The resulting folder will be named just like the system and will be created
in the I<OpenSLX-private-path>C</config>-folder (usually
C</var/opt/openslx/config>).
In that folder, a single subfolder C<default> will be created (representing
the default setup for all clients of that system). Within that folder, two
subfolders, C<initramfs> and C<rootfs> will be created.
The functions returns 1 if any folder had to be created and 0 if all the
required folders already existed.
