Describe the ReaR bug in detail¶
Hi,
When I run restore my system with ReaR it fails to boot afterwards.
I researched and found that it added a line in the System Boot sequence
for every time I tried to recover the system.
How can I resolve it so it won't act this way?

The local.conf content is:
OUTPUT=USB

BACKUP_URL=usb:///dev/disk/by-label/REAR-000
ONLY_INCLUDE_VG=( "os" )
USB_UEFI_PART_SIZE="1000"

@AmosMes
I am not at all a UEFI expert so in general
I can neither actually help with debugging UEFI related issues
nor can I fix UEFI related issues (except exceptions).
I added "waiting for info" because I do not understand
what you are talking about.
Problably I am somehow dumb or slow witted or whatever
and all is totally obvious for you and others.
In this case others who understand what goes on would
remove the "waiting for info" tag and proceed here.
But I do not have your particular environment
so I am just looking at your textual description
and from what I read I can not at all imagine
what exactly happens in your specific case.
FYI:
There is no such thing as "UEFI BIOS", cf.
https://github.com/rear/rear/issues/2276#issuecomment-558641223
to avoid confusion I recommend to use the word BIOS
only if you mean the legacy firmware in PC architecture
and also when you use the firmware in legacy BIOS mode
but the word EFI or UEFI if you mean nowadays firmware
that you use in its native way (i.e. as [U]EFI bootloader)
and the word firmware as generic name for such kind of software.
There is no such thing as BIOS that is UEFI capable
(old BIOS does not support [U]EFI) but there is firmware
that supports UEFI but can also run in legacy BIOS mode.
