A set of desktop sessions to be created with

{manpage}`gnome-session(1)`. This gnome-session configuration generates
|
|
both the `.desktop` file and systemd units to be able to support both
|
|
the built-in and the systemd-managed GNOME session.

Each of the attribute name will be used as the identifier of the

desktop environment.

::: {.tip}
|

While you can make identifiers in any way, it is encouraged to stick to
|
|
a naming scheme. The recommended method is a reverse DNS-like scheme
|
|
preferably with a domain name you own (e.g.,
|
|
`com.example.MoseyBranch`).
