* [Buildroot] [PATCH 1/1] busybox: Make S01logging source a default file.

The default syslog parameters are to keep only 200-400 KiB of logs,
which is very few if there is a spammy daemon on the system, or a daemon
that fails and then spams errors that hides the original problem.

Make S01logging source a /etc/default/logging file where these
parameters can be overridden.

Instead of '-e', we typically use '-r'.

Other than that, looks good. Could you send v2 with this change?

Unrelated to your patch, but passing '-n' (Run in foreground) looks
strange since we are daemonizing those processes anyway. Do you know any
good reason for this?

 I do: these daemons don't create a PID file, and if they daemonize and
start-stop-daemon creates the PID file, the PID logged in there will be wrong
(it will be the PID of the exited parent).

 Regards,
 Arnout

which is very few if there is a spammy daemon on the system, or a daemon
