As Laine says, please make sure this gets into 1.2.13-maint because it currently affects all 1.2.13 / Rawhide users. Also, why isn't there a regression test that would have picked this up? A trivial reproducer is: $ guestfish -a /dev/null --network run but any test case that launches a guest with a network interface as non-root would have caught this.
