Re: [Ltib] Support for %Post section of .spec file?

[ltib]

Hi Stuart,

Thanks for the quick response. I thought that the point of my patch was
to ensure that the %post section does execute on the machine that
installs the RPM, but maybe I'm just confused. It seems to do that
for me on my system, but I suppose it could be that I have a special case.

If I have different packages that want to add things to rc.local,
how can the packages automatically edit the rc.local file and
what do  I need to do (if anything) to get them to run
when my target system boots?

Thanks again, LTIB is great!
