[Bug 1038093] Re: [regression] Fedora17 and ArchLinux dont appear in GRUB menu

[YannUbuntu]

Bug is still present in Quantal: the os-prober of Ubuntu 12.10 does not
detect Fedora17 when Fedora17 is not mounted.

** Description changed:

- The os-prober of Ubuntu 12.04 (and 12.10) does not detect Fedora when
- Fedora's partition is unmounted (which is frequent). Consequence: Fedora
- does not appear in Ubuntu's GRUB menu.
+ The os-prober of Ubuntu 12.04 and 12.10 does not detect Fedora/ArchLinux
+ when Fedora/ArchLinux's partition is unmounted (which is frequent).
+ Consequence: Fedora/ArchLinux does not appear in Ubuntu's GRUB menu.
  
- WORKAROUND: mount the Fedora partition before doing update-grub in
- Ubuntu.
+ This bug did not exist with the os-prober of 11.10, so it is a
+ regression of os-prober.
+ 
+ WORKAROUND: mount the Fedora/ArchLinux partition before doing update-
+ grub in Ubuntu.
