Just adding fails:
E: 10mount: E: boost::filesystem::create_directory: Operation not supported: "/var/lib/schroot/mount/sid-ka-sbuild-1401909931-44836/dev/shm"
% mkdir /dev/shm
mkdir: cannot create directory '/dev/shm': Operation not supported
mounting the tmpfs on /run/shm and symlinking works well. I'll try
figure out what kfreebsd-* has done pre /run/shm
