Sure. If you look back in the message that started this thread there are
snippets of code.
The initial message was asking if there was any interest. (Or implicitly,
any objections.) I wasn't going to polish things like documentation if
somebody pointed out a fatal flaw.

We don't need anything for that since you can set the owner to ntp.
There is a capability for that. It covers all file access, not just /dev/
Bypass file read, write, and execute permission checks. (DAC is
an abbreviation of "discretionary access control".)

No. I have a script that I use as a wrapper for install. I put it in there
because that was the simplest way for me to get off the ground and see if it
I may need help fixing the waf install stuff. (I haven't looked yet.)
These are my opinions. I hate spam.
