cfuse and ceph.conf

[Fyodor Ustinov]

Hi!

As I understand with -m key cfuse should not require ceph.conf.

But:

root@st8:~# cfuse -m 10.5.51.230:6789 /stor01
common_init: unable to open config file.
root@st8:~#

Workaround:

root@st8:~# cfuse -c /dev/null -m 10.5.51.230:6789 /stor01
failed to open log file '/var/log/ceph/client.admin.log': error 2: No 
such file or directory

WBR,
     Fyodor.

P.S. BTW, where ".." directory?
P.P.S. I'm starting to feel myself like QA.

It does need a config, to even know whether it should attempt
cryptographic authentication or not (and where to find the key, etc).

It could be changed to do things more like the kernel client,
but as is, it always requires a config file.

Oh, heh, that's interesting.

It seems "." and ".." are optional, according to POSIX:

I couldn't figure out how to make a (correct) .. when writing the 
original fuse glue layer way back when.

Hmm, it looks like sshfs generates one, so it's at lesat possible.  It's 
probably simple enough to fix.
