With this patch, systemd-inhibit outputs a descriptive message when
desktopManagerHandlesLidAndPower=true (the default).
Before the patch:
$ systemd-inhibit
Who: /nix/store/[...]-xsession [...] (UID 1000/cassou, PID 18561/systemd-inhibit)
What: handle-power-key:handle-lid-switch
Why: Unknown reason
Mode: block
After the patch:
$ systemd-inhibit
Who: /nix/store/[...]-xsession [...] (UID 1000/cassou, PID 18561/systemd-inhibit)
What: handle-power-key:handle-lid-switch
Why: See NixOS configuration option 'services.xserver.displayManager.desktopManagerHandlesLidAndPower' for more information.
Mode: block
This solves the problem of e.g. mutt not finding mail unless the user
sets MAIL=/var/spool/mail/$USER.
The default MAIL variable seems come from bash. Reasons for adding
symlink instead of changing MAIL default in bash:
- No need to rebuild world
- FHS recommends /var/mail over /var/spool/mail anyway[1]. Better fix
NixOS mail location than change MAIL in bash to something that doesn't
work on non-NixOS (however unlikely that users run nixpkgs bash on a
non-NixOS distro...).

Better replace the double quotes in 'echo "${commands}"' with single
quotes, to prevent the shell from doing command substitution etc. at
configuration build time.
Currently the module hardcodes the systemd service user to "marathon".
With this change one would not need to create an extra systemd config to
override the user.
So why would one need to override the Marathon user? Some apps require
root access to run. You can't run those with Marathon unless you
override the default user to root. Marathon also provides a
`--mesos_user` command line flag which allows you to run apps using
arbitrary users. You need to run the framework as root to enable this
functionality.
JVMs exit with exit code 128+signal when receiving a (terminating)
signal. This means graceful termination of a JVM will result in 143, so
add that to `SuccessExitStatus` in systemd service unit.
- Usage of docker containerizer is currently hardcoded, this PR makes it
optional. Default is to enable it if docker is enabled.
- Make IP address to listen on part of service configuration.
The man page for ssh-keygen(1) has a section "MODULI GENERATION" that describes
how to generate your own moduli file. The following script might also be helpful:
| #! /usr/bin/env bash
|
| moduliFiles=()
|
| generateModuli()
| {
| ssh-keygen -G "moduli-$1.candidates" -b "$1"
| ssh-keygen -T "moduli-$1" -f "moduli-$1.candidates"
| rm "moduli-$1.candidates"
| }
|
| for (( i=0 ; i <= 16 ; ++i )); do
| let bitSize="2048 + i * 128"
| generateModuli "$bitSize" &
| moduliFiles+=( "moduli-$bitSize" )
| done
| wait
|
| echo >moduli "# Time Type Tests Tries Size Generator Modulus"
| cat >>moduli "${moduliFiles[@]}"
| rm "${moduliFiles[@]}"
Note that generating moduli takes a long time, i.e. several hours on a fast
machine!
