=head1 NAME

B<packimage> - Packs the stateless image from the chroot file system.

=head1 SYNOPSIS

I<packimage [-h| --help]>

I<packimage  [-v| --version]>


I<packimage [-o OS] [ -p profile] [-a architecture] [-m method]>

I<packimage imagename>

=head1 DESCRIPTION

Packs the stateless image from the chroot file system into a file system to be
sent to the node for a diskless install.
The install dir is setup by using "installdir" attribute set in the site table.
The nodetype table "profile" attribute for the node should reflect the profile of the install image.

If no I<imagename> is specified, this command uses the os image definition files from /install/custom/netboot/[os] directory first. If not found, it falls back to the default directory  /opt/xcat/share/xcat/netboot/[os]. 
If a I<imagename> is specified, this command will get all the necessary os image definition files from the I<osimage> and I<linuximage> tables.

=head1 Parameters

I<imagename> specifies the name of a os image definition to be used. The specification for the image is storted in the I<osimage> table and I<linuximage> table.

I<packimage  -o fedora8 -p compute -a x86_64>

This would use the package information from the /install/custom/netboot/fedora/compute* files first. If not found it uses /opt/xcat/share/xcat/netboot/fedora/compute* files.
