- Add `imageName` and `imageBaseName` options similar to the `isoName`
and `isoBaseName` options
- Make the filename of the iso match what iso-image.nix does
- Generate a nix-support/hydra-build-products like iso-image.nix does
Add another option for debugging instead. Lots of users have been
complaining about this default behaviour.
This patch also cleans up the EFI bootloader entries in the ISO.
This version should have more conventional regexes that work across many
platforms and regex engines. This is an issue because up until Nix 1.11,
Nix called out to the libc regex matcher, which behaved differently on
Darwin and Linux. And in Nix 1.12, we're moving to std::regex which will
also behave differently here.
And yes, I do actually evaluate make-disk-image.nix on Darwin ;)
Currently, if you try to build a NixOS config including channel.nix, e.g.:
nix-build -I nixpkgs=. -I nixos-config=nixos/modules/installer/cd-dvd/installation-cd-minimal.nix nixos -A config.system.build.isoImage
twice in a row, you end up with two different build results. This is
caused by the 'result' symlink of the first build affecting the channel
contents of the second build.
If we use filterSource with a predicate that ignores the 'result'
symlinks, the problem is gone. Do the same thing for VIM/Emacs
swap/backup files to avoid even more 'spurious' rebuilds.
Additionally, filter out the '.git' directory at the same time, as we
'rm -rf' it from the result anyway. This avoids a considerable amount of
unnecessary file I/O copying and deleting the .git directory.
Turns out all variants of start.elf and fixup.dat are needed (depending
on what's in config.txt). I was under the mistaken impression that you
were supposed to rename one of the variants to switch using them, but
nope.
The profile minimal has several drawbacks: no man pages, unusual 'dbus'
lib that makes many X11 pieces to rebuild, etc.
With xz compression in the squashfs, despite these additions, the iso is
smaller than what it was in 16.09.
- RPi3 successfully gets to U-Boot, but then fails to boot the kernel
due to a missing device tree file. This should get added to the 4.8
kernel release once this patch is merged: https://lkml.org/lkml/2016/6/1/841
- RPi2 is not tested, but it should successfully boot the NixOS image.
This command was useful when NixOS was spread across multiple
repositories, but now it's pretty pointless (and obfuscates what
happens, i.e. "git clone git://github.com/NixOS/nixpkgs.git").
