This should have been done initially, as otherwise it gets awfully
awkward to boot into new generations by default.
This system-specific image wasn't expected to be long-lived, thus why it
didn't end up being polished much.
Reality shows us we may be stuck with it for a bit longer, so let's make
it easier to use for new users.
we use stdenv.hostPlatform.uname.processor, which I believe is just like
`uname -p`.
Example values:
```
(import <nixpkgs> { system = "x86_64-linux"; }).stdenv.hostPlatform.uname.processor
"x86_64"
(import <nixpkgs> { system = "aarch64-linux"; }).stdenv.hostPlatform.uname.processor
aarch64
(import <nixpkgs> { system = "armv7l-linux"; }).stdenv.hostPlatform.uname.processor
"armv7l"
```
The volumeID will now be in the format of:
nixos-$EDITON-$RELEASE-$ARCH
an example for the minimal image would look like:
nixos-minimal-20.09-x86-64-linux
Note we're not using wayland default in the graphical media because it
could cause headaches for Nvidia users. But the session is still available
if someone logs out.
In 87a19e9048 I merged staging-next into master using the GitHub gui as intended.
In ac241fb7a5 I merged master into staging-next for the next staging cycle, however, I accidentally pushed it to master.
Thinking this may cause trouble, I reverted it in 0be87c7979. This was however wrong, as it "removed" master.
This reverts commit 0be87c7979.
I merged master into staging-next but accidentally pushed it to master.
This should get us back to 87a19e9048.
This reverts commit ac241fb7a5, reversing
changes made to 76a439239e.
When 'grafting' '/nix/store/<hash>-loopback.cfg' from disk onto
'/boot/grub/loopback.cfg' on the iso, the parent 'grub' directory does not
exist yet. In this case it is automatically created and inherits its
attributes, including timestamp, from /nix/store.
This is correct/expected/intentional behavior of xorriso, but has the
undesired result of leaking the timestamps of /nix/store into the iso. For
this reason we put the loopback.cfg in a
'/nix/store/<hash>-loopback.cfg/grub/loopback.cfg' instead, so it will inherit
the attributes from the correctly-timestamped
'/nix/store/<hash>-loopback.cfg/grub' directory.
For the same reason we move '/EFI/boot/efi-background.png' down in the list
so it is grafted after its parent '/EFI/boot' directory is created with
the correct timestamp.

Slim is abandoned and won't work with wayland.
It's in our best interest to use the display-manager
that makes most sense for Plasma5, sddm.
We've already moved on from it being default in #30890
and the graphical.nix profile, which the virtualbox profile uses,
has sddm anyway.
There's many reason why it is and is going to
continue to be difficult to do this:
1. All display-managers (excluding slim) default PAM rules
disallow root auto login.
2. We can't use wayland
3. We have to use system-wide pulseaudio
4. It could break applications in the session.
This happened to dolphin in plasma5
in the past.
This is a growing technical debt, let's just use
passwordless sudo.
This will keep configuration configuring the size of the /boot partition
still build, while showing the deprecation warning.
In 99.9% of cases I assume ignoring the configuration is better, as the
sd-image builder already is pretty opinionated in that matter.
The slack, seemingly, accounted for more than the minimum required for
slack plus the two partitions.
This change makes the gap a somewhat abstracted amount, but is not
configurable within the derivation.
The current FAT32 partition is kept as it is required for the Raspberry
Pi family of hardware. It is where the firmware is kept.
The partition is kept bootable, and the boot files kept in there until
the following commits, to keep all commits of this series individually
bootable.
This will reduce the confusion at boot, where the only thing visible is
the last message from u-boot; where it looks like the board is
hung, while in reality it's likely resizing partitions.

Prior to this commit an installation over serial via syslinux would
involve:
1. setting bitrate to BIOS's bitrate (typically 115200)
2. setting bitrate to syslinux's bitrate (38400)
3. setting bitrate to stty's bitrate (115200)
By changing syslinux's bitrate to 115200, an installation over serial
is a smoother experience, and consistent with the GRUB2 installation
which is also 115200 bps.
[root@nixos:~]# stty
speed 115200 baud; line = 0;
-brkint ixoff iutf8
-iexten
In a future commit I will add default serial terminals to the syslinux
kernel lines.
cleanSource does not appear to work correctly in this case. The path
does not get coerced to a string, resulting in a dangling symlink
produced in channel.nix. Not sure why, but this
seems to fix it.
Fixes#51025.
/cc @elvishjericco
This, paired with the previous commit, ensures the channel won't be held
back from a kernel upgrade and a non-building sd image, while still
having a new-kernel variant available.

b Batch mode. Optimized for huge recursive copies, but less secure if a crash happens during the copy.
```
It seems the "less secure if a crash happens" does not need a crash to
happen.
With batch mode:
```
/[...]/.
Start (0) does not point to parent (___)
```
For pretty much everything copied in.
Without batch mode, everything passes `fsck`.
See #51150

Because when I see "config.system.build.manual.manual" after I forgot
what it means I ask "Why do I need that second `.manual` there again?".
Doesn't happen with `config.system.build.manual.manualHTML`.
This is a 277K (as of right now) addition that can greatly help in some
last recourse scenarios. The specific rEFInd setup will not be able to
boot the installer image, but this is not why it has been added. It has
been added to make use of its volumes scanning capabilities to boot
existing EFI images on the target computer, which is sometimes necessary
with buggy EFI. While is isn't NixOS's job to fix buggy EFI, shipping
this small bit with the installer will help the unlucky few.
Example scenario: two wildly different EFI implementation I have
encountered have fatal flaws in which they sometimes will lose all the
settings, this includes boot configuration. This is compounded by the
fact that the two specific and distinct implementation do not allow
manually adding ESP paths from their interface. The only recourse is to
let the EFI boot the default paths, EFI/boot/boot{platform}.efi, which
is not a default location used by the NixOS bootloaders. rEFInd is able
to scan the volumes and detect the existing efi bootloaders, and boot
them successfully.
