Package: obnam
version: 1.17-1
We are seeing test failures with obnam on the raspbian autobuilders
(which use btrfs).
Having seen similar issues in the past i'm pretty sure this is a btrfs
related issue rather than an issue related to anything we changed in
raspbian. Specifically as I understand it nlink behaves differently
under btrfs than under other filesystem.
Unfortunately I don't have a plain Debian environment on btrfs handy
to make absolutely sure.
A build log from the latest version in raspbian stretch can be found at
http://buildd.raspbian.org/status/fetch.php?pkg=obnam&arch=armhf
ver=1.17-1&stamp=1442300722 , relavent parts are quoted below.
