chkconfig for ubuntu or other debian based linux systems



As I’ve mentioned I’ve got an ubuntu based test system. Most of my linux experience has been from a red-hat derivitive-based background and for that, at the command line, you have chkconfig which is a good tool for checking the configuration of services to run at startup. It is a red-hat derivitive thing… However, I found this forum post where someone contributed a “chkconfig” script that does the same thing. I tried it and it’s somewhat slow compared to it’s red-hat derivitive counterpart, but…. it does the job.


This script was posted by jbharrison on the ubuntu forums…. copied here for reference/mirroring/convenience.
