- run commands
- resource control
- run control
- runtime configuration
Personally, I'd go with run control, because ESR says so.

His footnote says:
The ‘rc’ suffix goes back to Unix's grandparent, CTSS.
It had a command-script feature called "runcom". Early
Unixes used ‘rc’ for the name of the operating system's
boot script, as a tribute to CTSS runcom.
Wikipedia chooses "run commands" as the default long-form, but admits that context should determine word choice.
While not historically precise, rc may also be pronou-
nced as "run control", because an rc file controls how
a program runs. For instance, the editor Vim looks for
and reads the contents of the .vimrc file to determine
its initial configuration. The most sensible pronunci-
ation depends on the function of the file: to start
something up, or to control how something starts up.
