Is it really surprising that systemd (like many other tools)
accepts values of yes/no, 1/0, and on/off in addition to
true/false for boolean settings?
It is documented in systemd.syntax(7), though I imagine many
people don't read all of the docs (which are already
sprawling and massive). Adding more to it may not help.
FWIW, the documentation says:
Boolean arguments used in configuration files can be
written in various formats. For positive settings the
strings 1, yes, true and on are equivalent. For negative
settings, the strings 0, no, false and off are
equivalent.
