We only care about /nix/store because its contents might be out of
sync with /nix/var/nix/db. Syncing other filesystems might cause
unnecessary delays or hangs (e.g. I encountered a case where an NFS
mount was taking a very long time to sync).
This is based on a prototype Nicolas B. Pierron worked on during a
discussion we had at FOSDEM.
A new version with a workaround for problems of the reverted original.
Discussion: https://github.com/NixOS/nixpkgs/commit/3f2566689
The implicit behavior of pulling it out of the classpath seemed not
to work properly and could be thrown off by other things on the
classpath also providing the properties file. This guarantees that
our settings stick.
We now make it happen later in the boot process so that multi-user
has already activated, so as to not run afoul of the logic in
switch-to-configuration.pl. It's not my favorite solution, but at
least it works. Also added a check to the VM test to catch the failure
so we don't break in future.
Fixes#23121
phpfpm currently uses `readFile` to read the php.ini file from the
phpPackage. This causes php to be build at evaluation time.
This eliminates the use of readFile and builds the php.ini at build
time.
This reverts commit 29caa185a7.
Not clear what the proper thing to do is. cf94cdb59b renders this
question mostly moot. Reverting before 17.03 branch to avoid a repeat
of #19054.
reason:
- We currently have an open discussion regarding a more modular
firewall (https://github.com/NixOS/nixpkgs/issues/23181) and
leaving null makes future extension easier.
- the current default might not cover all use cases (different ssh port)
and might break setups, if applied blindly
If a package's meta has `knownVulnerabilities`, like so:
stdenv.mkDerivation {
name = "foobar-1.2.3";
...
meta.knownVulnerabilities = [
"CVE-0000-00000: remote code execution"
"CVE-0000-00001: local privilege escalation"
];
}
and a user attempts to install the package, they will be greeted with
a warning indicating that maybe they don't want to install it:
error: Package ‘foobar-1.2.3’ in ‘...default.nix:20’ is marked as insecure, refusing to evaluate.
Known issues:
- CVE-0000-00000: remote code execution
- CVE-0000-00001: local privilege escalation
You can install it anyway by whitelisting this package, using the
following methods:
a) for `nixos-rebuild` you can add ‘foobar-1.2.3’ to
`nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
like so:
{
nixpkgs.config.permittedInsecurePackages = [
"foobar-1.2.3"
];
}
b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
‘foobar-1.2.3’ to `permittedInsecurePackages` in
~/.config/nixpkgs/config.nix, like so:
{
permittedInsecurePackages = [
"foobar-1.2.3"
];
}
Adding either of these configurations will permit this specific
version to be installed. A third option also exists:
NIXPKGS_ALLOW_INSECURE=1 nix-build ...
though I specifically avoided having a global file-based toggle to
disable this check. This way, users don't disable it once in order to
get a single package, and then don't realize future packages are
insecure.
When dhcpcd instead of networkd is used, the network-online.target behaved
the same as network.target, resulting in broken services that need a working
network connectivity when being started.
This commit makes dhcpcd wait for a lease and makes it wanted by
network-online.target. In turn, network-online.target is now wanted by
multi-user.target, so it will be activated at every boot.
This makes make-disk-image.nix slightly more consistent with other image
builders we have. Unfortunately I duplicated some code in doing so, but
this is temporary duplication on the path to consolidating everything.
See https://github.com/NixOS/nixpkgs/issues/23052 for more details on that.
I'm also exposing the option in the amazon-image.nix maintainer module.
Using toJSON on a string value works because the allowed JSON escape
sequences is almost a subset of the systemd allowed escape sequences.
The only exception is `\/` which JSON allows but systemd doesn't.
Luckily this sequence isn't required and toJSON don't produce it making
the result valid for systemd consumption.
Examples of things that this fixes are environment variables with double
quotes or newlines.
Since systemd version 232 the install subcommand of bootctl opens the
loader.conf with fopen() modes "wxe", where the "e" stands for
exclusive, so the call will fail if the file exists.
For installing the boot loader just once this is fine, but if we're
using NIXOS_INSTALL_BOOTLOADER on a systemd where the bootloader is
already present this will fail.
Exactly this is done within the simpleUefiGummiboot installer test,
where nixos-install is called twice and thus the bootloader is also
installed twice, resulting in an error during the fopen call:
Failed to open loader.conf for writing: File exists
Removing the file prior to calling bootctl should fix this.
I've tested this using the installer.simpleUefiGummiboot test and it now
succeeds.

This leads to the following error when trying to install a new machine
where the machine ID wasn't yet initialized during boot:
Failed to get machine did: No such file or directory
In addition this was also detected by the simpleUefiGummiboot installer
test.
So let's generate a fallback machine ID by using
systemd-machine-id-setup before actually running bootctl.
Tested this by running the installer.simpleUefiGummiboot test, it still
fails but not because of the machine ID.

Add link to "Configuration" chapter from "Changing the Configuration" section.
Also, fix grammar error.
