This is the end of the configuration that the end-user will use.
They will specify an attribute set that contains the name for the
group, so they can say
`accounts.email.accounts.<aname>.groups.<gname>` to access the
configuration for the group with the name `<gname>`.
A group is a grouping of channels together, so that many channels with
very different names can be handled as a single entity.
Groups are unique in mbsync because they will shadow channels that
have the same name on the command-line.
A channel is a relationship between 2 directories/boxes/mailboxes
between the local machine (slave) and the remote mail server (master).
Each channel must be given at least:
* an account-unique name
* a pattern for which mailboxes to sync from master
* a pattern for what directory where that mail ends up on the
slave
Additional options can be added later.
Emacs populates 'exec-path' at launch from the 'PATH' environment
variable. Likewise, the emacs derivation from nixpkgs populates
'load-path' from the 'NIX_PROFILES' variable. As neither of these are
available by default in the systemd user manager, revert to the
previous behavior of launching the Emacs daemon from a login shell.

PR #1355
Add 'services.emacs.socketActivation.enable' for generating an
'emacs.socket' systemd unit.
Emacs since version 26 has supported socket activation, whereby an
external process manager such as systemd listens on a socket and passes
it to the Emacs daemon when the manager launches it. This improves
startup time of the user session and avoids launching the daemon when not
needed, for example when launching the user session via SSH.
This implementation hard-codes the socket path to the default for the
version of 'programs.emacs.finalPackage', because systemd does not
perform shell expansion in the socket unit's 'ListenStream' parameter
and it seems like an advanced use-case to change the socket path. Shell
expansion would be desirable as the socket path usually resides in
directories such as $XDG_RUNTIME_DIR or $TMPDIR.
Tests were added to verify behavior in the following cases:
- Emacs service with socket activation disabled
- Emacs 26 with socket activation enabled
- Emacs 27 with socket activation enabled

This change stops update-mime-database from running unless the
`share/mime/packages` directory is writable. For some reason it
appears to be read-only on WSL1.
