No, mock is to *build* RPMs inside a chroot jail, not to build RPMs of
programs that *run* inside a chroot jail.
mock is useful if you have a 64-bit machine and you want to build
32-bit RPMs. By creating a pure 32-bit environment inside a chroot you
can be sure that the binaries you are buiding inside that environment
will not be
accidentally linked against the 64-bit libraries that exist on your
main environment. If you have a 32-bit OS running and you want to
build a 32-bit RPM, you don't have to bother with mock.
By the way, I have rebuilt several Fedora Core 8, 9 and even
10/development SRPMs in CentOS 5 with a fair rate of success. As long
as they are not core components (such as kernel, glibc, perl, python)
I believe you might be successful with your rebuild. Of course,
sometimes you will have to adjust the specfile to reflect names that
have changed in a new version of Fedora to match the ones used in
Fedora Core 6/CentOS 5, but other than that it's not to hard to make
it build and work. In any case, I suggest you first test your RPM in a
test machine, do not install it directly on a production machine,
because if you break it you got to keep the pieces.
Good luck with your rebuild!
Filipe
