Re: shellcommands not executing - lock problem?

I've had similar problems sometimes when a command name results in an
identical lock name.

My solution in the past has been to trick cfengine with a slightly
different path.

I'll use /usr/bin/rsync for one command, and /usr/bin/./rsync for
another.
