This behavior is fairly consistent among supervisors. The use of STDERR
typically is left to the administrator to decide; more commonly, it's
simply tied off into the STDOUT stream for ease of use.

This is probably a problem with your shell. The shebang specified might
point to an actual sh and not something like bash, ash, dash, etc. I don't
have a reference handy but I suspect that you are seeing failure messages
for "exec" because the shell doesn't support that built-in.

If you encounter this, change the first line to /bin/bash or /bin/ash or
/bin/dash and see if that resolves the issue.

Gentoo may be mapping /bin/sh to bash/ash/something else, but I don't
know. I would suggest finding out.

I'll post a companion log script in a moment.

You shouldn't need to create the group normally, which may indicate a
separate issue.

Try this run script in your ./svcdef/dbus/log directory. It's lifted
straight from the source at as the
./svcdef/.log/run-svlogd script. Please note that you may need to change
the group name after chown, and the shell in the first line to meet your

#!/bin/shexec 2>&1# determine our parent's nameSVNAME=$( basename $(
echo `pwd` | sed 's/log//' ) )# bring up svlogd logging into a
subdirectory that has the parent's name.[ -d /var/log/$SVNAME ] ||
mkdir -p /var/log/$SVNAME ; chown :adm /var/log/$SVNAME[ -d main ] ||
ln -s /var/log/$SVNAME mainexec /usr/bin/svlogd -tt main

If you are using Gentoo, I would recommend looking at Toki Clover's
implementation at

I hope this helps.
