Subject: Allow to run in daemon mode without log file.
X-Git-Tag: v0.1.7~20
X-Git-Url: http://git.tuebingen.mpg.de/?p=dss.git;a=commitdiff_plain;h=d13861de884e6d76fb854d1869e7c4373d619b6e;ds=sidebyside

Allow to run in daemon mode without log file.

It's kind of silly to insist in having a log file in daemon mode.

This commit removes the dependency of --daemon on --logfile and makes
/dev/null the default log file. Consequently, running dss --daemon
--run without specifying --logfile no longer fails, and nothing will
be logged by default.

The documentation is updated accordingly.
