Solved Kernel 4.11.6 UEFI VARS and efibootmgr
I noticed that efibootmgr is not usable with standard fog kernel (EFI variables are not supported on this system).
I used the documentation https://wiki.fogproject.org/wiki/index.php?title=Build_TomElliott_Kernel#Build_TomElliott_Kernel_for_FOG_0.33b_and_newer to compile the kernel and changed only this option:
EFI (Extensible Firmware Interface) Support <*> EFI Variable Support via sysfs
and now efibootmgr is working. Can you activate this option by default in the fog kernel ?
I’ve updated the current 4.11.6 kernels to include both the vars and the boot editing elements.
Hopefully this helps.
Hello @Tom-Elliott when we deploy new computers we want to configure EFI boot order via postdownloadscripts to modify default entries.
Usually if we just deploy image to the disk (including the EFI partition) it will not boot as-is. We have go to bios and add a new entry (this is for Dell desktop computers and Xubuntu images). If we can use efibootmgr from postdownloadscripts we will script this to avoid manual configuration after first imaging.
@Tom-Elliott Ahhh, fair enough, I couldn’t remember exactly what the issue was there.
@Quazz Most likely not seeing as booting newer mac’s don’t make it to the kernel in the first place. They’re stuck in iPXE (maybe not even that far?)
Might I ask what you’re using this for? This wasn’t added because it caused other problems (when I tested it).
Adding it is simple enough sure, but what other impacts does it have?
I wonder if this could potentially help with booting Macs on the newest firmwares?
