Which brings up the problem that's been bothering me about the 
all-in-config suggestion: Where do you put an argument that tells it where 
to find the config file, especially in cases where you might have 
different instances of the same program running from different config 
files, in parallel?  Are you going to put it in the config file?

(I'm thinking specifically of the solution I came up with for dhcpd not 
handling IPv4 and IPv6 in the same instance, where I ran it twice with 
different -cf options, though I think that might have been fixed in dhcpd 
since then, but I haven't tested that yet.  Yes, it was broken-ish, but 
sysconfig files letting you work around things like that is certainly 
helpful.)
