+# Reduce shutdown timeout from 90s to 10s.
+# If you rely on important tasks to successfully finish during the shutdown sequence, set the timeout to something greater than 90s.
+DefaultTimeoutStopSec=10s
+
+# Rationale:
+# This is done for the following reasons:
+# - 90s is too long for users to wait (they think it's hanging indefinitely, and they eventually just use their power button)
+# - Cups, minidlna have made this a buggy mess for years now and there's no sign of improvement for the near future
+# - This is a workaround many people have used in Mint, Ubuntu, Arch, Fedora and many other distributions, although reducing the start
+# timeout is known to possibly affect the journal, no adverse effects were reported after reducing the stop timeout.
+# - For our audience (desktop users), this makes a lot of sense. It would be different for a server, or a machine which relies on shutdown
+# scripts to perform important tasks, but for most people this fixes a very important issue and is unlikely to create new ones.
