Lock tinc into main memory.
This will prevent sensitive data like shared private keys to be written to the system swap files/partitions.
+This option is not supported on all platforms.
+
@item --logfile[=@var{file}]
Write log entries to a file instead of to the system logging facility.
If @var{file} is omitted, the default is @file{@value{localstatedir}/log/tinc.@var{netname}.log}.
Note also that tinc can't run scripts anymore (such as tinc-down or host-up),
unless it's setup to be runnable inside chroot environment.
+This option is not supported on all platforms.
@item -U, --user=@var{user}
Switch to the given @var{user} after initialization, at the same time as
chroot is performed (see --chroot above). With this option tinc drops
privileges, for added security.
+This option is not supported on all platforms.

@item --help
Display a short reminder of these runtime options and terminate.
