As far as rcorder goes, an empty script is just as good as a single null command: % cat precedence #!/bin/sh # # Persuade postgresql to start before spamassassin. # PROVIDE: precedence # REQUIRE: postgresql # BEFORE: spamd % rcorder /etc/rc.d/* /usr/local/etc/rc.d/* | grep -E 'postgresql|precedence|sa-spamd' /usr/local/etc/rc.d/postgresql /usr/local/etc/rc.d/precedence /usr/local/etc/rc.d/sa-spamd Hey -- I saved a whole two bytes.

An explanation written some 80 years ago;
'Because that way it will work'.

I had a similar problem about two years ago. One program required program "X" to load prior to it while program "Y" wanted to load it after it. It was causing a conflict. It is slightly difficult to explain in a few words. I had to manually check every file in the /usr/local/etc/rc.d directory to straighten it out. I believe that there is a way to have all of that information displayed without going through that much intervention; however, I do not remember how to do it at the moment. Anyway, in the "samba" file, it has this notation: # PROVIDE: nmbd smbd I don't know if that makes any difference or not. I have never had to move the starting order of samba around. I do know that in other applications, they appear to have their name in the "PROVIDE" line. For example, from the Postfix script: # PROVIDE: postfix mail -- Jerry ♔ Disclaimer: off-list followups get on-list replies or get ignored.

However any time you update vboxheadless you'll have to remember to add that modification back to the rc script. Using a separate file stops that being a problem. If you want to test that your changes are having the desired effect without having to reboot: # rcorder /etc/rc.d/* /usr/local/etc/rc.d/* which will print out the order all the rc-scripts would be run. (It includes all the scripts, not just the ones enabled in /etc/rc.conf, but that shouldn't matter.) Cheers, Matthew -- Dr Matthew J Seaman MA, D.Phil.
