Efivars is full
Encountered this issue on A Dell server
`Failed to create EFI Boot variable entry: No space left on device.` during bootloader install
Googling `DbocBoot` only shows one result https://bbs.archlinux.org/viewtopic.php?id=276175
Running `strings` on the `DbocBoot` entries show that they contain strings like `Windows Boot Manager` and `Ubuntu` and other old efi boot entries
`bcfg boot dump -v` in EFI shell does not show these variables, only `Boot*` variables
The fix is to remove `DbocBoot` entries
Normally the files are protected therefore it is necessary to remove the protection
`chattr -i /sys/firmware/efi/efivars/DbocBoot*`
Then they can be removed
`rm -vi /sys/firmware/efi/efivars/DbocBoot*`
During the next boot there may be a warning
`Warning: Corrupted BootOrder variable detected... Repaired` and the boot will continue as normal.
