It should not break your HDA and as a little example of what this can do, we included the famous memtest86+ memory test. See if you can run it by booting off the network after you install the package:
{{Code| yum -y install amahi-netboot}}
If this works well, we will be able to package other things as apps that are net-bootable!
Edit to add boot entries:
{{Code| vi /usrvar/sharelib/amahi-netboot/tftptftpboot/pxelinux.cfg/default}}
(This needs more documentation here!)
