(address . bug-guix@gnu.org)
Hello Guix,
I ran into this issue while doing a fresh install of Guix 0.8.2. I had
a typo in my declaration of the grub device (I had unintentionally left
out the leading "/" on "/dev/sda"), so 'guix system init' failed when
setting up grub. I fixed the typo in the OS config and reran 'guix
system init' but was greeted by an error about existing store
directories.
I ended up needing to remove the /mnt/var, /mnt/grub, and /mnt/gnu/store
before being able to successfully rerun 'guix system init'.
It would be useful for newcomers if recovering from mistakes were more
trivial.
