      • reasoning: To retrieve disk usage for any mounted filesystem (including the root fs) from outside the Snap environment…

The s1panel snap provides a real-time system dashboard and displays it on the S1 Mini PC’s built-in LCD screen. It can report onboard storage device statistics and visualize them on the front display. We use the <block-devices> interface to call statfs() and retrieve read-only details such as capacity and usage. No write operations are performed

So far, this is the only way I’ve been able to retrieve root filesystem info. With <block-devices>, the following command returns the expected data:

lsblk --fs --paths --list --exclude=7
 
/dev/mapper/ubuntu--vg-ubuntu--lv ext4        1.0            f01a8607-dcfb-4a5a-9743-c509943c5106    826.3G     4% /tmp
                                                                                                                   /root
                                                                                                                   /home
                                                                                                                   /etc

This allows statfs(“/root”) to return the correct usage information. Also, I currently have a “Manual review requested” status pending in the Builds section.

Many thanks in advance!

This makes sense for this snap. +1 (#voteFor) manual connection of the block-devices interface
