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

[Stuart Hughes]

Hi Chip,

Generally speaking you can't add a %post section into the spec files
that LTIB uses.  The reason is that these are normally expected to be
run on the machine that *installs* the rpm, which in this case is the
host and therefore would not work.

Currently the easiest way to do this is to add your own rc.local (or
some other startup script) to do what you want (drop it into a merge
directory).

Regards, Stuart
