the systemd.unit(5) discussion of wantedBy and requiredBy is in the
[Install] section, and thus focused on stateful 'systemctl enable'.
so, clarify that in NixOS, wantedBy & requiredBy are still what most
users want, and not to be confused with enabled.
Grub configs include the NixOS version and date they were built, now
systemd can have fun too:

This fixes NixOS/nixpkgs#26910.
old version of blkid used to output version information including libblkid version
when invoked with --help parameter
new version does not output libblkid version when invoked with --help parameter
fix is to invoke blkid with -V parameter to output version including libblkid in both cases
* systemd-boot-builder.py: add support for profiles
This will also list the generations of other profiles than `system` in
the boot menu. See the documentation of the `--profile-name` option of
nixos-rebuild for more information on profiles.
* Fix errors introduced by previous commit
Or else `services.udev.packages = [ bcache-tools ]` cannot be used.
To not break bcache in the initrd I'm modifying this in stage-1.nix:
- --replace /bin/sh ${extraUtils}/bin/sh
+ --replace ${bash}/bin/sh ${extraUtils}/bin/sh
Reasoning behind that change:
* If not modifying the /bin/sh pattern in any way, it will also match
${bash}/bin/sh, creating a broken path like
/nix/store/HASH-bash/nix/store/HASH-bash/bin/sh in the udev rule file.
* The addition of /bin/sh was done in 775f381a9e
("stage-1: add bcache support"). It seems somewhat plausible that
no new users have appeared since then and we can take this opportunity
to back out of this change without much fear of regressions.
If there _are_ regressions, they should be in the form of build time
errors, not runtime (boot), due to how the udev rule output is checked
for invalid path references. So low risk, IMHO.
* An alternative approach could be to copy the /bin/sh substitute rule
over to the non-initrd udev rules implementation in NixOS, but I think
this way is better:
- The rules file comes with a working path out of the box.
- We can use more precise pattern matching when modifying the udev
rules for the initrd.
The default font is unreadably small on some hidpi displays. This
makes it possible to specify a TrueType or OpenType font at any point
size, and it will automatically be converted to the format the Grub
uses.
Restructure the nixos-artwork to make it easy to selectively
incorporate other components from upstream without needing to download
the full package.
Until now only the Gnome_Dark wallpaper was included. Add other
wallpapers available in the package repository.
Since fat32 provides little recovery facilities after a crash,
it can leave the system in an unbootable state, when a crash/outage
happens shortly after an update. To decrease the likelihood of this
event sync the efi filesystem after each update.
Someone on IRC wanted to boot Fedora from another disk. While I'm not
too familiar with UEFI booting in conjunction with GRUB2 it took some
time to get it to work.
So in order to safe others from frustration I'm adding this as another
example to the extraEntries option.

This has surfaced since d990aa7163.
The "simpleUefiGummiboot" installer test fails since this commit,
because that commit introduced a small check to verify whether the store
was altered.
While installing NixOS for the first time, the store is usually in
/mnt/nix/store and without the read-only bind mount that's preventing
programs from altering the store.
So after nixos-install is done creating the system closure and setting
it as the active system profile, the bootloader is written from the
closure inside the chroot. The systemd-boot-builder is invoked during
this step, which adds .pyc files for various Python modules of the
Python 3 store path, which in turn invalidates the hash of the Python 3
store path itself.
At the time the system is booted up again, the nix-store is verified and
fails with something like this:
path /nix/store/zvm545rqc4d97caqq9h7344bnd06jhzb-python3-3.5.3 was
modified! expected hash

Running the interpreter with the -B argument prevents Python from

This reverts commit c2b56626f1.
It broke creating the manual. I suspect the descriptions are
auto-wrapped by <para> and </para>.

The LUKS header can be on another device (e.g. a USB stick). In my case
it can take up to two seconds until the partition on my USB stick is
available (i.e. the decryption fails without this patch). This will also
remove some redundancy by providing the shell function `wait_target` and
slightly improve the output (one "." per second and a success/failure
indication after 10 seconds instead of always printing "ok").
Restarting them is useless since the filesystem is already
checked. Worse, restarting them causes the filesystem to be unmounted.
Also remove an override for systemd-rkill@.service which no longer
exists.
