I'm interested in unpacking an rpm so I can get at the files without having to go through the install process. There don't seem to be any options for this using either the yum
or rpm
commands. My goal is to then modify and then rebuild the rpm. Is there a way to do this?

you could unpack rpm using command
rpm2cpio package.rpm | cpio -i --make-directories
If you want to modify package, the better way is to download package.src.rpm file, install it using rpm -i package.src.rpm
. This would place sources to /usr/src/redhat/SOURCES. You could patch sources and modify spec file located in /usr/src/redhat/SPECS/ and then rebuild package using
rpmbuild -bb /usr/src/redhat/SPECS/package.spec

yumdownloader (in yum-utils package) is handy for snagging srpms. Oct 28, 2009 at 14:19

the directory /usr/src/redhat should be created, when you install your first source rpm.– sumarOct 30, 2009 at 10:04
