=head1 NAME
slxos-export - OpenSLX-script to export a stage1-system (a.k.a. vendor-OS) into
a stage2-system (a.k.a. export).
The export itself can be done via several different types, e.g. via NFS or
via a squashfs inside of a network block device.
=head1 SYNOPSIS
slxos-export [options] <action>
=head3 Options
--help brief help message
--man show full documentation
--verbose show more information during execution
--version show version
=head3 Actions
=over 8
=item B<< add <vendor-OS-name> <export-type> >>
exports the vendor-OS with the given name using the given export type and
adds it to the config-DB, too
=item B<< list-exported >>
list all exported vendor-OSes
=item B<< list-installed >>
list all installed vendor-OSes
=item B<< list-types >>
list all supported export types
=item B<< remove <export-name> <export-type> >>
removes the export with the given name and export type from disk and
config-DB
=back
=head1 OPTIONS
=over 4
=item B<--help>
Prints a brief help message and exits.
=item B<--man>
Prints the manual page and exits.
=item B<--verbose>
Prints more information during execution of any action.
=item B<--version>
Prints the version and exits.
=back
=head1 EXAMPLES
=over 8
=head3 Exporting a Vendor-OS via NFS
=item B<< slxos-export add suse-10.2 nfs >>
Exports the installed vendor-OS suse-10.2 via nfs, the
resulting NFS-export will live in C</srv/openslx/export/nfs/suse-10.2>.
=back
=head3 Exporting a Vendor-OS via NBD-Squash
=over 8
=item B<< slxos-export add ubuntu-6.10 nbd-squash >>
Exports the installed vendor-OS ubuntu-6.10 via nbd-squash, the resulting
Squash-FS will live in C</srv/openslx/export/nbd-squash/ubuntu-6.10>.
=back
=head3 Removing an Export
=over 8
=item B<< slxos-export remove ubuntu-6.10 nbd-squash >>
Wipes the squash-FS of the export named 'ubuntu-6.10' from disk (i.e. the
file C</srv/openslx/export/nbd-squash/ubuntu-6.10> will be deleted) and
removes that export from the config-DB, too.
