Verify that we can still kick clients using our instructions in RTD and the changes don't cause any problems when UEFI and BIOS boot are simultaneously supported. A bug fix was made to have the code match the tftpboot README. It may be that the correct fix was to have the README match the code. So, the fix may break existing systems.
Also verify that adding simp_disk_crypt to the extras options in the tftpboot does encrypt the client and it bootstraps successfully. Some people have had a problm with it not rebooting. It will pause and ask for the encryption password and it should not.
NOTE: Only verify for client OS listed in the ticket. Full PXE boot testing is covered by other tickets.
