FC4 is using glibc 2.3 and FC5 uses glibc 2.4. If you want FC4 with glibc 2.3, just leave it alone. You may be able to run FC4 with FC5's glibc 2.4. But you will build packages that require glibc 2.4 and won't install on the FC4 machine. You won't be able to downgrade FC5 to glibc 2.3. Every package requires "libc.so.6(GLIBC_2.4)". If you need to build packages or software for FC4 while running FC5, you can use a chroot or virtualization. mock makes clean chroot's for building RPMs. You can do something similar for building software manually. For a while, I ran the FC5 rawhide as my primary distribution and chroot'ed to my old FC4 installation for running applications and doing FC4 development. Or you could use VMware or Xen for full virtualization. - Ian -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
