leveraging users.users.<user>.createHome instead of a preStart script.
preStart script is still required to ensure proper creation of logging
directory.
The list of public proxies is updated now and again and it's probably a
good idea to always work from the most recent list, rather than the one
that is shipped with the release. This can be crucial in case of
resolvers that are revealed to have gone rogue or otherwise have been
compromised.
Instead of using this option, please modify the dovecot package by means of an
override. For example:
nixpkgs.config.packageOverrides = super: {
dovecot = super.dovecot.override { withPgSQL = true; };
};
Closes https://github.com/NixOS/nixpkgs/issues/14097.
* Perform HTTP HEAD request instead of full GET (lighter weight)
* Don't log output of curl to the journal (it's noise/debug)
* Use explicit http:// URL scheme
* Reduce poll interval from 10s to 2s (respond to state changes
quicker). Probably not relevant on boot (lots of services compete for
the CPU), but online service restarts/reloads should be quicker.
* Pass --fail to curl (should be more robust against false positives)
* Use 4 space indent for shell code.
The current postStart code holds Jenkins off the "started" state until
Jenkins becomes idle. But it should be enough to wait until Jenkins
start handling HTTP requests to consider it "started".
More reasons why the current approach is bad and we should remove it,
from @coreyoconnor in
https://github.com/NixOS/nixpkgs/issues/14991#issuecomment-216572571:
1. Repeatedly curling for a specific human-readable string to
determine "Active" is fragile. For instance, what happens when jenkins
is localized?
2. The time jenkins takes to initializes is variable. This (at least
used to) depend on the number of jobs and any plugin upgrades requested.
3. Jenkins can be requested to restart from the UI. Which will not
affect the status of the service. This means that the service being
"active" does not imply jenkins is initialized. Downstream services
cannot assume jenkins is initialized if the service is active. Might
as well accept that and remove the initialized test from service
startup.
Fixes#14991.
A sane backend for recent brother scanners.
Depends on the presence of etc files generated by the
nixos module of the same name.
Supports network scanner specification through the
nixos module.
