Dear util-linux@, in Debian, udisks2 2.10.1-6 (autopkg-)tests fail with util-linux 2.40, but passed with 2.39. We are not yet sure if this is directly caused by util-linux, but it seems somewhat likely. I won't get to it this week (also re: stable v2.40.1), but maybe someone else has seen this failure already? > udisks2's autopkgtest fails when tried together with util-linux 2.40.

For context, Debian's util-linux 2.40-7 should have everything from 2.40 stable up to a8aa0b5f154a44557f5bae5a4027bdbfe42b0323. Chris
