At testlab run this test script and not found this bug in freevps-1.1.0.
======
[root_at_cp root]# ./testnfs.pl
Testing fcntl...
[root_at_cp root]#
cat locktest.lock
blabla[root_at_cp root]#
=======
after it share work correctly - dir can been changed and files been read.
for test share do mounting inside vps.
