I noticed it was installed just on one disk too... but I'm definitively
not an expert, infact one of the things I tried to fix this was:

grub-install /dev/sda
grub-install /dev/sdb

but I noticed the grub-pc/install_devices didn't change.

I'm reasonably sure that during installation I chose both but it
happened several month ago, so I won't bet on it... and I admit I
started to be too confident in how smoothly sid behave recently ;)

dpkg-reconfigure grub-pc

did the trick and now I can see both dev in grub-pc/install_devices

I upgraded, rebooted and now everything is fine

Unfortunately I can't roll back time to confirm that I actually chose
both at install time.

If there is any bug actually it should be related to older
versions/install and people should not be affected in the future.

thanks
