;; abort if they cannot. I could not figure out how to stop bzr
;; doing that, so just give it a temporary homedir for the duration.
;; http://bugs.launchpad.net/bzr/+bug/137407 ?
;;
;; Note that with bzr 2.x, this works:
;; mkdir /tmp/bzr
;; HOME=/nonexistent BZR_HOME=/tmp/bzr bzr status
;; but with brz 3.1, it complains:
;; "failed to open trace file: [Errno 13] Permission denied: '/nonexistent'"
;; which confuses vc-dir.
;; We can quieten brz by adding either BRZ_LOG=/dev/null, or
;; XDG_CACHE_HOME=/tmp/bzr (log defaults to XDG_CACHE_HOME/breezy/brz.log),
;; but it seems simpler to just set HOME to a newly created
;; temporary directory.
;; TODO does this means tests should be setting XDG_ variables (not
;; just HOME) to temporary values too?
