schroot has suddenly decided to throw errors whenever I use it:
prune# schroot --chroot jessie-amd64-sbuild --user=root
E: 20copyfiles: cp: cannot create regular file '/var/run/schroot/mount/jessie-amd64-sbuild-569a4fef-b267-4e4b-bb6c-da14e167ddee/etc/resolv.conf': Operation not permitted
E: jessie-amd64-sbuild-569a4fef-b267-4e4b-bb6c-da14e167ddee: Chroot setup failed: stage=setup-start
prune# schroot --chroot sid-amd64-sbuild --user=root
E: 20copyfiles: cp: cannot create regular file '/var/run/schroot/mount/sid-amd64-sbuild-b87ff7e8-a09e-47ee-be8d-8a407056d84c/etc/resolv.conf': Operation not permitted
E: sid-amd64-sbuild-b87ff7e8-a09e-47ee-be8d-8a407056d84c: Chroot setup failed: stage=setup-start
Anybody else seen similar problems?
