 Same problem here.
 
 After looking a bit in mount and mksnap_ffs, this seems due to a 
 difference in the way the snapshot is created : mount calls nmount(2), 
 while mksnap_ffs only calls mount(2). There might also be differences 
 in the options passed to the syscalls, that needs investigating.
 
 Note that mount sends a HUP signal to mountd after each successful mount 
 (including snapshots), while mksnap_ffs does not, however manually 
 restarting mountd after a mksnap_ffs does not exhibit the bug.
