# The other four XDG directories are very easy, but XDG_RUNTIME_DIR is

|
# complicated. It kinda needs to be managed by a systemwide supervisor, like
|
|
# systemd, in order to meet all of the XDG Base Directory specification's
|
|
# requirements? In particular, the directory is supposed to come into being
|
|
# when you log in, live as long as you have any active sessions, and be
|
|
# destroyed when you log out - none of this can easily be done from the shell
|
|
# environment alone, especially on an operating system like macOS where your
|
|
# graphical session wasn't spawned from a shell using something like .xinitrc.

|
|
# systemwide supervisor if it can possibly have been. If it hasn't - say,
|

# because we're on macOS - we'll compromise by using TMPDIR. Since TMPDIR has
|
|
# a different lifetime than XDG_RUNTIME_DIR is supposed to, this is an
|
|
# imperfect solution, but it's the best we can do.
