Hi,

This is with the latest snapshot.

This is minor because it was being formatted anyway, but the issue is that
I had created a raw unformatted partition outside of GUIX, but the GUIX
partitioner tool was seeing it as possessing a filesystem of EXT4 already,
when in fact it should have been blank. Maybe it is a trace of a previous
partition that was in the space, but this is odd, it should not have
detected a filesystem on a new blank partition.

This means it was not reading the partition table correctly.

Best,
Peter

Could you explain this part?  E.g., did you run ‘wipefs -a’ to 
erase the old file system metadata?  Partition tables do not 
specify file system information.

Guix can take responsibility only for its own drive partitioning 
code (which, by most accounts I've heard, could certainly be 
improved); otherwise it's the user's and/or tools' responsibility 
to correctly wipe the underlying data.

Kind regards,

T G-R
