Description of problem: I'm trying to upgrade my Fedora 11 x86_64 system to Fedora 13 x86_64 via DVD install method. At the upgrade boot loader GUI screen, the message at the top of the screen is: "The installer is unable to detect the boot loader currently in use on your system" and the "Update boot loader configuration" option is greyed out. Version-Release number of selected component (if applicable): Fedora 13 x86_64 release How reproducible: 100% Steps to Reproduce: 1. Have a working Fedora 11 system which has no /etc/sysconfig/grub and (no line starting with #boot= in /etc/grub.conf or /etc/grub.conf being an absolute symbolic link) 2. Try to upgrade Actual results: Fail Expected results: Win Additional info: booty/checkbootloader.py:getBootloaderTypeAndBoot() is too fragile. On my system /etc/sysconfig/grub did not exist. /etc/grub.conf was an absolute symbolic link. /boot/grub/grub.conf didn't have #boot= line. Please please please autodetect this sort of crap by probing in case of failure. A scan of the MBR of the device which I was installing too (and which contained /boot) would have worked. Worst case, the grub.conf could still have been updated by scanning /boot if the stage 1 couldn't be confirmed. Oh, and the code should really be updated to perform a readlink on /etc/grub.conf

Was it anaconda? Is there any reason we should suppose this information can be removed from the system? > > Please please please autodetect this sort of crap by probing in case of > failure.

We must set a limit of how much a system can be modified to be still upgradable and falling back to detection doesn't seem to be worth raising it. It seems fragile and unreliable, note that you can install on more disks, there can be grub bootloaders of other systems in MBR, etc... If you come with a patch, we will consider it. > Oh, and the code should really be updated to perform a readlink on > /etc/grub.conf What problem is it supposed to resolve?
This message is a reminder that Fedora 13 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 13. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '13'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 13's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 13 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
