Hi Efraim,

that would be great. I'm looking forward to try them out.

Since we are already talking about arm64 here, do you have experience
with transparent huge pages on aarch64?

I would love to get some feedback on this one:

https://lists.gnu.org/archive/html/guix-patches/2023-02/msg00698.html

Do you know if any of the aarch64 build machines configured with a page
size > 4K? If so, I think that patch could help building more packages
on that architecture.

Thanks, Roman.
