Comment (by arma):

 Though. If you change pastly's torrc to no longer include
 {{{CookieAuthentication 1}}}, Tor starts up, but its log file has a bunch
 of other complaints, e.g.
 {{{
 Jun 26 17:23:50.000 [warn] Couldn't open "./datadir-3hop/unverified-
 microdesc-consensus.tmp" (./datadir-3hop/unverified-microdesc-consensus)
 for writing: No such file or directory
 Jun 26 17:23:50.000 [warn] Couldn't open "./datadir-3hop/cached-certs.tmp"
 (./datadir-3hop/cached-certs) for writing: No such file or directory
 Jun 26 17:23:50.000 [warn] Error writing certificates to disk.
 Jun 26 17:23:50.000 [warn] Failed to unlink ./datadir-3hop/unverified-
 microdesc-consensus: No such file or directory
 }}}

 It looks like get_datadir_fname() in general can't handle having a
 relative path for a datadir.
