Re: [yocto] Arch Linux - Python Newer than Recommend i.e. post 3.12

[Nicholas Krause <xerofoify@gmail.com>]

Greetings,
I'm on kirkenstone currently. So backporting the patches is probably 
best. However, what's the longterm strategy around this as its been a 
program for several years on more bleeding edge distributions i.e. Arch? 
Even when were talking mainline its a problem with Arch sometimes.

Thanks,
Nick
