Subject: Print deprecation notice when running SUID
X-Git-Url: https://git.mdlowis.com/?a=commitdiff_plain;h=c7aaa8dd616782537b8624eacabd3ee7020d69a3;p=proto%2Flabwc.git

Print deprecation notice when running SUID

Tracking swaywm/sway@e1db1f8

Add soft deprecation warning to highlight future intent of removing the
code which drops SUID privileges. libseat now has a better alternative in
the form of seatd-launch which uses the normal seatd daemon & libseat
backend and takes care of SUID.

Fixes issue #212
