Title: Adding Services
Post by: Mark Fifield on January 07, 2003, 05:29:46 PM

Hi,

I have a probably quick and hopefully simple question...

I need to add a service (ACAP on Port 674) to the list in /etc/services my question is, is this safe? When I open /etc/services file in vi, the first few lines say DO NOT MODIFY THIS FILE!!! Which I suppose is there for a reason. So can I safely edit this file without having adverse affects elsewhere??

Thanx in advance!
Mark

It won't hurt anything to edit the file. However, your changes will be lost on reboot.

http://www.e-smith.org/custom/ (The "customizing the system" link from the front page of e-smith.org.)

Each config file is created from a directory full of fragments. There is a custom directory where you can place additional or modified fragments. Then if you want to revert back to the original, just delete your custom fragments, and everything is fine again.

What do the next few lines of the file say?

That's not true. No templated file is re-expanded at reboot, but all templated files are re-expanded at one time or another. At upgrade is one time when you can be sure that every templated file is re-expanded.
