So, I'm building custom yum RPM's for our campus mirrors. So I'm wondering, can RedHat-8.0 run a yum-2.0 RPM built on Redhat9? Or do I need to build a yum RPM for each distro I support? If the latter, is than an easy way to maybe make a postin script ont he rpm to build the python for the machine it's being built on so I don;t have to build for 7.1, 7.2, 7.3, 8, and 9? Thanks! -n -- ------------------------------------------- nathan hruby <nhruby@xxxxxxx> uga enterprise information technology services production systems support metaphysically wrinkle-free -------------------------------------------
