Last modified: 2009-02-05 07:31:39 EST
Description of problem: advanced filepermissions gone Version-Release number of selected component (if applicable): all How reproducible: everytime Steps to Reproduce: 1. restore file permissions for fedora by: rpm -qa | rmp --setperms --setugids 2. 3. Actual results: i susspect that advanced file permissions like sticky bit, SUID and SGID are whiped because some commands behave different. For example: when loggid in as an regular user isuing: user$ su - password: authentication failed while using the correct root password Expected results: Additional info: Is there a way to restore those permissions whitout re-installing the system, or is there an overview for fedora of files/directories using these filepermision so i can restore them by hand.
Moving to rpm component.
The order matters here, --setperms and --setugids are two different operations, and changing uid/gid causes suid/sgid bits to be reset, undoing part of the work of --setperms. This'll do the trick (for all packages, to selectively reset replace -a with package names) # rpm --setugids --setperms -a No bug here, except perhaps insufficient documentation on these popt aliases.
