The pxe.lrp package is not a real package in the sense that you cannot save it as you would do for any other LEAF package. Once the pxe.lrp package is loaded it will replace some of the original Bering files from the initrd.lrp and the root.lrp packages in order to make your Bering box PXE bootable. It will also bring to the initrd.lrp package the tftp client that will download the file from your server.

More precisely, the content of the package is as follow:

/var/lib/lrpkg/initrd.list		a modified initrd.list in order to save new files in initrd.lrp
/var/lib/lrpkg/initrd.conf		a modified initrd.conf to be able to edit initrd.pxe.conf
/var/lib/lrpkg/initrd.pxe.conf		the pxe configuration file
/var/lib/lrpkg/root.linuxrc		a modified linuxrc using tftp to download the packages
/usr/bin/tftp				the tftp client from P. Anvin
/usr/sbin/lrcfg.back			a modified lrcfg.back script to allow backups on tftp server and floppies
/usr/sbin/lrcfg.back.script		a modified lrcfg.back.script to allow backups on tftp server and floppies

The installation is basically a two steps process:
