With this patch, systemd-inhibit outputs a descriptive message when
desktopManagerHandlesLidAndPower=true (the default).
Before the patch:
$ systemd-inhibit
Who: /nix/store/[...]-xsession [...] (UID 1000/cassou, PID 18561/systemd-inhibit)
What: handle-power-key:handle-lid-switch
Why: Unknown reason
Mode: block
After the patch:
$ systemd-inhibit
Who: /nix/store/[...]-xsession [...] (UID 1000/cassou, PID 18561/systemd-inhibit)
What: handle-power-key:handle-lid-switch
Why: See NixOS configuration option 'services.xserver.displayManager.desktopManagerHandlesLidAndPower' for more information.
Mode: block
This solves the problem that modprobe does not know about $MODULE_DIR
when run via sudo, and instead wrongly tries to read /lib/modules/:
$ sudo strace -efile modprobe foo |& grep modules
open("/lib/modules/3.14.37/modules.softdep", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/lib/modules/3.14.37/modules.dep.bin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/lib/modules/3.14.37/modules.dep.bin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
open("/lib/modules/3.14.37/modules.alias.bin", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory)
Without this patch, one would have to use sudo -E (preserves environment
vars). But that option is reserved for sudo users with extra rights
(SETENV), so it's not a solution.
environment.sessionVariables are set by PAM, so they are included in the
environment used by sudo.
We already have separate tests for checking whether the ISO boots
correctly, so it's not necessary to do that here. So now
tests/installer.nix just tests nixos-install, from a regular NixOS VM
that uses the host's Nix store. This makes running the tests more
convenient because we don't have to build a new ISO after every
change.
install-cd: Include nixos-artwork to fix installer tests
With the move from storing grub images in the nixpkgs repo to storing them in the nix store, we broke the installer tests as the iso does not contain the artwork needed for the grub splash. This commit fixes the inclusion of the artwork in the iso.
