I agree, but someone has to write it...

I don't intend to reimplement any of this. I just needed a way to dump
stuff to a file instead of a tty. It's intended for usage during
development of services, not for deployment. As Ludo mentioned it's
not quite as simple as just redirecting stdout/sderr and needs some
support in shepherd. Someone who actually runs services that require
high availability will have to contribute better logging support ;)

Many services expect stdout/stderr to be handled. I don't think that
every service needs to reimplement basic logging functionality.
systemd allows to set a services stdout and stderr to either
journal/syslog/file/tty, so new services written for systemd expect
this to be taken care of.

New lines are a pretty good guess.
