daemontools's Issues

svc cannot send the service SIGUSR1 and SIGUSR2. Needs extending.

Problem:

A service monitored by supervise is listening for the signals
SIGUSR1 and/or SIGUSR2. It is expecting these signals which will
trigger actions in the service.

While under supervision by daemontools, the is no practical way to
send these signals to the service.

Proposed Solution:

The normal way to send signals to a service under supervision is to
use the svc program. For example svc -h /service/myservice will send
a SIGHUP to the service.

Augmenting svc by adding new options to extend the functionality to
include sending the desired signals will resolve this issue.

The new options -v and -w are proposed for sending SIGUSR1 and
SIGUSR2, respectively.
