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...).

Commit 159fed47bc (nixos/grub: Fix video display on efi) changed BIOS
systems to start in non-text mode as well. Enable FB_VESA to get a
framebuffer console on BIOS systems. Change FRAMEBUFFER_CONSOLE to 'y'
instead of the default 'm' to so the user doesn't need to manually load
the fbcon module anymore.
Other distros have similar defaults, at least on Arch:
CONFIG_FB_VESA=y
CONFIG_FRAMEBUFFER_CONSOLE=y
and on Ubuntu (12.04):
CONFIG_FB_VESA=m
CONFIG_FRAMEBUFFER_CONSOLE=y

Better replace the double quotes in 'echo "${commands}"' with single
quotes, to prevent the shell from doing command substitution etc. at
configuration build time.
The issue was that grub was not building the default entry which would
leave systems unbootable. This can now be safely reverted as the default
entry is being built once again.
This reverts commit fd1fb0403c.
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.
