Re: cannot mount directories at work nodes.

Update: I tried ami-a5c42dcc this time and it works greatly.
Please update the part "*Latest Stable AMI IDs*: ami-d1c42db8 (*i386*),
ami-a19e71c8 (*x86_64*) " at the project home page so that other people
do not need to waist a lot of time on them like me. :(

Best wishes

Sincerely yours
