Description David Walser 2015-10-22 21:30:42 CEST

Multiple times on our Mageia 5 workstations at work, I have seen /boot/grub/device.map disappear, renamed to device.map.old (with a slightly older, but empty, device.map.backup also present).  It has happened again, and checking journalctl, I can match up the timestamps on device.map.old with some log messages.  The modification time matches up with these:
bootloader-config[2752]: writing grub config to /boot/grub/menu.lst
[RPM][1991]: install kernel-server-4.1.8-1.mga5-1-1.mga5.i586: success

That doesn't appear to the problem, as the contents of the file are still good.

The ctime and access time (ctime is changed when a file is renamed) match with:
bootloader-config[2318]: writing grub config to /boot/grub/menu.lst
[RPM][2305]: erase kernel-server-3.19.8-3.mga5-1-1.mga5.i586: success

So, that appears to be when it misbehaves.

With device.map gone, future kernel installs don't fully work and you can't run drakboot --boot.

Can you test the patches in bug #16918 please? Thanks
At least a tester!

While I had seen this happen multiple times, I haven't seen it in a while, and I have removed some kernels.  I don't have a way to reliably reproduce it, so I can't test for it.  The description of the patches sounds legitimate though, so feel free to commit them.
