Hi! Icecat with Rust may have long time installing. In my PC Intel 2.16GHZ - even for 1 day.

Swap: I configured swap with this line under (operating-system):

(operating-system

....

  (swap-devices '("/dev/sda2"))

...

)

You need to part your disk and also mkswap, swapon  on the /dev/sda2 or another. Look at manual 6.1.4.3 Disk Partitioning

Thank you. It's finished while I'm going out.

I found my guix system has no swap. I think swap setting is necessary in file-systems configuration.
