Subject: save: detect missing metastore via ENOENT not EACCES
X-Git-Url: https://arthur.ath.cx/gitweb/?a=commitdiff_plain;h=0840163bf2d3e9467807772283677856bb799887;p=bup.git

save: detect missing metastore via ENOENT not EACCES

While we might also eventually want to handle EACCES, ENOENT should be
what we want for the current handler, i.e. "does it exist at all".
