If we don't have writable grubenv, recordfail doesn't work, which means our
quickboot behavior - with a timeout of 0 - leaves the user without a
reliable way to access the boot menu if they're on UEFI, because unlike
BIOS, UEFI does not support checking the state of modifier keys (i.e.
holding down shift at boot is not detectable).
Handle this corner case by always using a non-zero timeout on EFI when
save_env doesn't work.
Reuse GRUB_RECORDFAIL_TIMEOUT to avoid introducing another variable.
In this case, we need both the signed shim as /EFI/BOOT/BOOTXXX.EFI
and signed Grub as /EFI/BOOT/grubXXX.efi.
Also install the BOOTXXX.CSV into /EFI/debian, and FBXXX.EFI into
/EFI/BOOT/ so that it can work when needed (*iff* we're updating the
NVRAM).

When creating T32->A32 transition jumps, the relocation code in grub
will generate trampolines. These trampolines live in the .data section
of our PE binary which means they are not marked as executable.
This misbehavior was unmasked by commit a51f953f4e ("mkimage: Align
efi sections on 4k boundary") which made the X/NX boundary more obvious
because everything became page aligned.
To put things into proper order, let's move the arm trampolines into the

Some UEFI firmware is easily provoked into running out of space in its
variable storage. This is usually due to certain kernel drivers (e.g.
pstore), but regardless of the cause it can cause grub-install to fail
because it currently asks efibootmgr to delete and re-add entries, and
the deletion often doesn't result in an immediate garbage collection.
Writing variables frequently also increases wear on the NVRAM which may
have limited write cycles. For these reasons, it's desirable to find a
way to minimise writes while still allowing grub-install to ensure that
a suitable boot entry exists.
Unfortunately, efibootmgr doesn't offer an interface that would let
grub-install do this. It doesn't in general make very much effort to
minimise writes; it doesn't allow modifying an existing Boot* variable
entry, except in certain limited ways; and current versions don't have a
way to export the expected variable data so that grub-install can
compare it to the current data. While it would be possible (and perhaps
desirable?) to add at least some of this to efibootmgr, that would still
leave the problem that there isn't a good upstreamable way for
grub-install to guarantee that it has a new enough version of
efibootmgr. In any case, it's cumbersome and slow for grub-install to
have to fork efibootmgr to get things done.
Fortunately, a few years ago Peter Jones helpfully factored out a
substantial part of efibootmgr to the efivar and efiboot libraries, and
so it's now possible to have grub-install use those directly. We still
have to use some code from efibootmgr, but much less than would
previously have been necessary.
grub-install now reuses existing boot entries where possible, and avoids
writing to variables when the new contents are the same as the old
contents. In the common upgrade case where nothing needs to change, it
no longer writes to NVRAM at all. It's also now slightly faster, since
using libefivar is faster than forking efibootmgr.

The vendor class identifier with the string "HTTPClient" is used to denote the

URL already contains the server address for the boot file. For DHCP6 config,
there's no difference definition in existing config as dhcp6.bootfile-url can

If other operating systems are installed, then automatically unhide the

otherwise boot immediately. If keystatus is not available, then fall
