Thanks, James. I've just run this on a rawhide system: koji download-build yum-3.4.0-1.fc16 then this to install the 3 .rpm files: yum install yum-* To test it, I set the permissions: chmod go+r /var/lib/yum/rpmdb-indexes/* then ran this (with my usual umask of 077): yum upgrade --skip-broken It didn't install anything (but did report dependency problems with many boost-* js, js-devel, openbios-common packages), but did change the permissions: $ ls -l /var/lib/yum/rpmdb-indexes total 152 -rw-rw-rw-. 1 root root 2878 Apr 16 00:07 conflicts -rw-r--r--. 1 root root 40862 Apr 16 00:06 file-requires -rw-r--r--. 1 root root 106402 Apr 16 00:06 pkgtups-checksums -rw-r--r--. 1 root root 45 Apr 16 00:06 version Oops. Now "conflicts" is world writable. _______________________________________________ Yum mailing list Yum@xxxxxxxxxxxxxxxxx http://lists.baseurl.org/mailman/listinfo/yum
