It seems the mount is waiting for lockd.  On diskless install,
dbootstrap try to mount nfs partition without "nolock" option.  For
workaround, you can do "Execute a Shell" and type

 # mount -o nolock server:/path /target

instead of "Mount a Previously-Initialized Partition" on diskless
install.

Isn't this a bug of dbootstrap ?  Here is a patch.
