[9fans] Fwd: cifsd

[root81@gmail.com (Sergey Kornilovich)]

Thanks, now everything works fine.

But if you want that windows clients can connect any vacfile (in /lib/vac or
$home/lib/vac), you must modify the file /bin/9fs.

This is: vacfs -m /n/`{basename $1.vac} `{cat $score}
To this: vacfs -p -m /n/`{basename $1} `{cat $ score}
(-p Disables permission checking)
If anyone knows a more elegant way to do it, I'll be glad to hear.
