General Logging
===============
**Syntax:** `log size:200k count:5`
Log rotation for run/task/services using the `log` sub-option with
redirection to a log file. Global setting, applies to all services.
The size can be given as bytes, without a specifier, or in `k`, `M`,
or `G`, e.g. `size:10M`, or `size:3G`. A value of `size:0` disables
log rotation. The default is `200k`.
The count value is recommended to be between 1-5, with a default 5.
Setting count to 0 means the logfile will be truncated when the MAX
size limit is reached.
Redirecting Output
------------------
The `run`, `task`, and `service` stanzas also allow the keyword `log` to
redirect `stderr` and `stdout` of the application to a file or syslog
using the native `logit` tool. This is useful for programs that do not
support syslog on their own, which is sometimes the case when running
in the foreground.
The full syntax is:
log:/path/to/file
log:prio:facility.level,tag:ident
log:console
log:null
log
Default `prio` is `daemon.info` and default `tag` is the basename of the
service or run/task command.
Log rotation is controlled using the global `log` setting.
**Example:**
service log:prio:user.warn,tag:ntpd /sbin/ntpd pool.ntp.org -- NTP daemon
