Discovery image issues with UEFI - BOOTIF
Description
Hi
All our physical boxes are UEFI enabled, I'm trying to setup bare metal discovery but running into issues because of the BOOTIF=01-$net_default_mac
Been troubleshooting this issues several days, could able to found mac address that the discovery image associates is having semicolon at the end which is wrong, thus dhcp server fails to lease an ip address.
BOOTIF=01-14-02-ec-94-78-10:
correct value should be as below.
BOOTIF=01-14-02-ec-94-78-10
Have attached attached grub.cfg config file and the screenshots.
I think the discovery image should also insmod regexp and do the regexp filter inroder to set the correct mac address.

Hello,
using RHEL 7.4 or more recent foreman-bootloaders package? There is a bug in RHEL 7.4 (regression) in Grub2, it appends extra colon to MAC. I created BZ and it is currently being worked on by RHEL engineers.

The workaround is to downgrade to some older version of grub2 which does not have it. Make sure you regenerate grub2 on TFTP server. You can use our tarball, grab oldest version there:

http://downloads.theforeman.org/foreman-bootloaders/
I think it has grub2 from RHEL 7.3 which is not affected by this bug.
