Description Barry Jackson 2015-04-07 01:07:52 CEST 
Description of problem:
In Mageia 4 if the bootloader is switched from grub legacy to grub2 using drakboot this works fine and the change is seamless.

If the change is made AFTER upgrade to Mageia 5 it just fails silently, and the MBR still has legacy grub.

Running grub2-install /dev/sda in the upgraded system writes a new MBR without problem and on the next boot grub2 works.

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Create Mga4 in VM with legacy grub - fully update it
2. Take snapshot
3. Use drakboot to switch bootloader to grub2 and test it
4. Restore snapshot and upgrade to Mageia 5
5. Reboot and take snapshot
6. use drakboot to switch bootloader to grub2. No errors, but bootloader is not installed, reboot is still using legacy.


Reproducible:

Please look for drakbtoot actions using "journalctl SYSLOG_FACILITY=17" (or /var/log/explanations if you have rsyslog installed)
