Hello all:  

Thanks (particularly Mr. Sapiro) for the help yesterday.  

I'm working on a server which is expected to host multiple instances of mailman 
in the next week or so.  In the interest of privilege separation, each instance 
is being built to run as a distinct system user, specific to that instance of 
the mailman installation, but distinct from each other.  

I just debugged an issue which had stacked up mail in the mta's que for 
forty-some hours before it was caught (yes, I'm checking out this tracker 
package described in a message a moment or so ago).  In the end, what it took 
was touch .../.../mailman/data/virtual-mailman to create a file being sought by 
the mta, then restarting the qrunners which had all failed for some reason.  

I am unfamiliar with gentoo, being used by our host server, but am making 
progress in figuring it out.  Apparently there is a file somewhere in /etc 
which does what I'm used to having Debian do with /etc/init.d scripts and 
runlevels.  

I want to write a perl or shell script to occasionally check that the qrunners 
are still running and if they are not, to restart them.  (I can't afford 
downtime like this).  My question is this.  Since each instance uses a distinct 
uid and gid, is it possible to have root handle this task in its crontab?  Or 
am I going to actually have to su - to each mailman user involved to restart 
the qrunners, or to install crontabs for each that will handle this job?  

One other issue, while we're on the subject of disaster recovery, which files 
and directories do I need to include in my daily back-ups?  And can anyone 
point me to a how-to that might describe how to restore from such backups 
should the unthinkable ever happen?
