>Description:
There is a problem with dot files or directories when a subdirectory template is directly copied to the MFS filesystem.
A file /conf/$ip/root/.foobar will not be copied, because the expression in line 303 cp -Rp $j/* /$subdir will only copy non dot files.


>How-To-Repeat:
Create a dot file in /conf/$ip/root (for example .foobar) and start a diskless client. There would be a MFS filesystem mounted on /root, but without .foobar.
>Fix:
Adding a simple cp -Rp $j/.* will result in a copy of the whole parent directory. So the easiest way would be to replace the copy with a tar command.
