When you have separate btrfs subvolumes for /gnu and /var/guix, you'll
encounter this error running `guix system init /mnt/etc/config.scm /mnt`
when it tries to copy things to /mnt. My guess is that guix is trying to
remove one of them but fails as they're mounted.
I encountered this issue while I tried installing guix system on my main
laptop. But I have encountered this before [1]. When I installed guix
system on my secondary laptop. I worked around it back then by using
guix-0.15.0.
For my secondary laptop I have this layout
| subvol | Mountpoint | Comment |
|-----------------------+------------+-----------------|
| __current/guixsd-root | / | root for GuixSD |
| __current/grub | /boot/grub | grub config |
| __current/guix | /var/guix | guix stuff |
| __current/gnu | /gnu | Store etc |
| __current/home | /home | home partition |
For my main laptop I tried:
| subvol | Mountpoint | Comment |
|--------+------------+----------------|
| @ | / | root for Guix |
| @grub | /boot/grub | grub config |
| @guix | /var/guix | guix stuff |
| @gnu | /gnu | Store etc |
| @home | /home | home partition |
Found another thread that also had this issue [2], and the same
workaround worked for me. I.e. simplified the layout:
| subvol | Mountpoint | Comment |
|-----------+------------+----------------|
| @ | / | root for Guix |
| @home | /home | home partition |
This seems to just be an issue when running guix system init, as I've
been using my secondary laptop with separate subvolumes for /gnu and
/var/guix without any issues since 0.15.
The guix version I used to install my main laptop with was
1.1.0-25.44c6e6f. I generated it with
guix system disk-image --file-system-type=iso9660 \
gnu/system/install.scm
As described in the manual.
Thanks
