I guess you have way too many TLAs here...

"Enable Comprehensive System Accounting Job Accounting" . Ouch. So you
do not even know how to use those accronyms correctly.
I guess you should invent some better naming.
> + Comprehensive System Accounting (CSA) provides job level
> + accounting of resource usage. The accounting records are
> + written by the kernel into a file. CSA user level scripts
> + and commands process the binary accounting records and
> + combine them by job identifier within system boot uptime
> + periods. These accounting records are then used to produce
> + reports and charge fees to users.

> + accounting records portion of this feature to be a loadable
> + module. Say N here if you do not want job level accounting
> + (the default).

> + The CSA commands and scripts package needs to be installed

...long text and it *still* does not tell me what it is good for.

We normally drop back compatibility at merge...
