We are running over 6000 tests by now and they take around 5 minutes
on faster machines and tests alot of components that endusers will not
actually be using. It is sufficient if we run them on package upgrades
and in the passthrough test.
This dependency has been added in 65eae4d, when NixOS switched to
systemd, as a substitute for the previous udevtrigger and hasn't been
touched since. It's probably unneeded as the upstream unit[1] doesn't
do it and I haven't found any mention of any problem in NixOS or the
upstream issue trackers.

This will make it easier to track specifically where queries are being
made from (assuming a `log_line_prefix` that includes `%a` in the
postgres configuration).
- Actually run tcsd as tss/tss
- Install a udev rule to set /dev/tpm* permissions
- Remove systemd-udev-settle dependency, use dev-tpm0.device instead
- Use systemd-tmpfiles to set up the state directory
- Add documentation URI to tcsd.service
This module cannot be easily tested with a NixOS test due to the TPM
dependency. Technically, one could be emulated using swtpm[1], but this
is not packaged in Nixpkgs. If you computer has a real TPM you can do a
passthrough in Qemu, but this requires running the VM as root and of
course it's not determinstic:
$ nix build -f nixos vm --arg configuration '
{
virtualisation.qemu.options = [
"-tpmdev passthrough,id=tpm0,path=/dev/tpm0,cancel-path=/sys/class/tpm/tpm0/cancel"
"-device tpm-tis,tpmdev=tpm0"
];
users.users.root.hashedPassword = "";
services.tcsd.enable = true;
}'
After starting the VM, log in as root, you can check the service has
started with `systemctl status tcsd`.

- Actually use the zfsSupport option
- Add documentation URI to lxd.service
- Add lxd.socket to enable socket activatation
- Add proper dependencies and remove systemd-udev-settle from lxd.service
- Set up /var/lib/lxc/rootfs using systemd.tmpfiles
- Configure safe start and shutdown of lxd.service
- Configure restart on failures of lxd.service
- Use --netlink to avoid systemd-udev-settle[1]
- Run daemon in foreground which is preferred with systemd
- Add unit documentation
- Write ExecStart directly, no need for a script
