How to install guix system from existing linux with guix package manager? |

How would I install Guix system from an existing Linux that has the guix
package manager on it (aka from a foreign distro)?
Specifically I have Guix installed on Arch Linux on an encrypted btrfs ssd. I
have a @home subvolume mounted on /home. Currently /gnu/store is not a
subvolume, but I'd like to reuse it for guix system. I also have the efi system
partition for uefi boot.
What I'd like to do is install Guix system and boot from a subvolume. Ideally
the guix fstab would be like this:
@guix-root is mounted on / on guix system
@gnu-store is mounted on /gnu/store on guix system and shared between arch and
guix
@home is mounted on /home and shared between arch and guix
So I think the steps are as follows:
0. backup data (just in case)
1. move /gnu/store to subvolume
2. install Guix system manually with the following file systems:
(mapped-devices
(list (mapped-device
(source (uuid "my-uuid"))
(target "cryptroot")
(type luks-device-mapping))))
(file-systems (append
(list (file-system
(device (file-system-label "cryptroot"))
(mount-point "/")
(type "btrfs")
(options "subvol=@guix-root")
(dependencies mapped-devices))
(file-system
(device (file-system-label "cryptroot"))
(mount-point "/gnu/store")
(type "btrfs")
(options "subvol=@gnu-store")
(dependencies mapped-devices))
(file-system
(device (file-system-label "efi"))
(mount-point "/boot/efi")
(type "vfat")))
%base-file-systems))
3. configure uefi to boot guix grub by default
WDYT? any tips/suggestions?
