It can can take a few seconds for the generator to initialize in slow
environments. Switch to using systemctl is-system-running which should
reflect the system is fully booted.
In #283893 we realized that not only 6.7, but also testing is affected.
And with more stable kernels following, we'll probably want to test
against all of them whether Rust support is working fine. As long as
it's not the default at least, then we should probably move this to
`kernel-generic`.
Every kernel that's new enough to support `rust-out-of-tree-module` (and
`linux_testing`) is part of this text matrix.
With the update of systemd to v255, the repart tool switched to use 4K
sector sizes by default. This change sets the appliance-repart-image
test to use a sector size of 512B to fit in with the existing NixOS VM
test infrastructure using qemu disks with 512B sector sizes.
The current build of livebook does not work with the new [Livebook
Teams](https://livebook.dev/teams/) features. The problem can be observed by
running the current version of livebook, adding a new team and going to the team
page. The process will crash and the team page will show a 500 error.
The base of the problem is that the escript build method is not officially
supported. This commit changes the livebook package to use the `mix release`
workflow, which is also the one used to build the official Docker container.
Unfortunately, the binary built with `mix release` does not support command line
arguments like the `escript` binary does. Instead, users need to pass in most of
the configuration as environment variables, as documented
[here](https://hexdocs.pm/livebook/readme.html#environment-variables). As a
result, this commit also changes the Livebook service to reflect this new way of
configuring Livebook.
Finally, the Livebook release configuration specifically excludes the
ERTS (Erlang Runtime System), which means that the resulting release cannot run
without Erlang installed.
I have tested the results (both of the package and the service) locally.
Fixes#241482.
Also fix test putting cluster in unhealthy `POOL_APP_NOT_ENABLED` state;
this seems to be the default state with Ceph 18.2.1 at least,
and it does not hurt to fix it now already in the way the Ceph docs say.
Also revert "nixosTests.ceph-single-node: remove dashboard check"
This reverts commit 41b27d7f4b.
