Trying to add Arch to GRUB2 with GRUB Customizer

Question

Ok, I have GRUB2 and I installed Arch and now I'm inside my Mint 14 environment using GRUB Customizer trying to add Arch to Grub. How do I do that?

Last time I tried doing this in ANY Ubuntu-based distribution, os-prober wouldn't pick up ArchLinux at all, regardless of whether Arch was mounted or not (rendering shulamy's question pointless). I do note that os-prober in Ubuntu would pick up Windows, regardless of whether the Windows partitions were mounted or not.
For these situations, the options I would say to you are EITHER:
1) Write the Arch entry manually into /etc/grub.d/40_custom on Mint; OR
2) Install Mint's grub onto the Mint partition, not the disk, install Arch's grub to the MBR/disk and chainload from Arch's grub into Mint's.
[As a side note, this seems to be a bug with Ubuntu's implementation of os-prober. In Fedora, Arch, Gentoo and so on, os-prober will quite happily find any and all installations of Arch.]
Wouldn't it be better in this case not to install Ubuntu's version at all and to just use Arch's? Why use one grub to load another, especially when grub really does not like being installed to a partition?
