CentOS - Feb 2007 - How do I build a modified rpm (Another newbie question)?

I made a minor change to the XFS package (in the unpacked source files),
but I can't figure out which rpmbuild option to use to build from that
changed source file (instead of re-unpacking all the source files,
overwriting all the source files, etc.).

Please assist/explain.

Thanks.

you'd better generate patch files instead of modifying directly source 
files: once generated, you store them in SOURCES/ directory and modify 
the .spec file to include them in the package generation.

good overview of RPM & spec file:

more complete informations about RPM and their generation:

 From a mid/long-term perspective, it will be easier for you to manage 
it, especially if you also generate the .src.rpm source package file: it 
will contains your modify .spec file and also the patches you've created.
