Arch Linux

Description:
When running virt-builder the command fails and no image is produced.
The relevant line in the output when it fails seems to be:
supermin: root UUID is longer than 16 bytes

I think this has been fixed upstream

Additional info:
* package version: 1.42.0-5

This seems like it is caused by changes to the file package

It seems like this is fixed upstream:
https://github.com/libguestfs/libguestfs/commit/278d0d3226f4bdb7c6586986ca46d0a25c976fe4

Steps to reproduce:
Run:
LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1 virt-builder fedora-34 -o /tmp/fedora-34.img

produces the following output:
