Read-Only Filesystem Error opening tor lockfile in 0.2.6.9 but not 0.2.5.12
tor_0.2.5.12-1~d70.wheezy+1_amd64 can open the tor lockfile, but tor-0.2.6.9 gets a EROFS error.
The error happens in the first open() call in tor_open_cloexec, when called from tor_lockfile_lock. But I can't work out why.
aexl will write to tor-dev to provide more information.
