Every time I update my system it has a pre-transaction hook to create a new snapshot and regenerate a grub configuration file with the new snapshot. I love this. It's a great idea.
The only issue is that I am dual booting with mainline Arch, and the grub configuration takes around 5-10 minutes because it gets stuck before outputting:
Found Arch Linux on /dev/sda5
Is there anything I can do to make this go faster? I still use my old Arch setup from time to time when I want something super minimal, I have it set up with Xmonad and just use basic tools, so I don't want to get rid of it.
