FreeBSD mary-teresa 8.2-STABLE FreeBSD 8.2-STABLE #0: Tue Jun 7 17:56:08 EEST 2011 root at mary-teresa:/usr/obj/usr/src/sys/otrada.3 amd64
>Description:
You need to copy the skeleton directories without files contained therein, only subdirectories.
Problems arose with the symlinks.
Symlinks are ignored mtree and rsync.

>How-To-Repeat:
Creating a test directory with a symlink:
#!/bin/sh
symlink="ghgh gugh seee udjd"
mkdir -p /tmp/test/All /tmp/test-copy
cd /tmp/test/All
for i in $symlink; do
mkdir ../$i
ln -s ../$i $i
done
Script copying the skeleton directory using mtree:
#!/bin/sh
from_dir=/tmp/test
to_dir=/tmp/test-copy
mkdir -p $to_dir
cd $from_dir/;
mtree -c -d -i -n -k link,uname,gname,mode,flags > $to_dir/dir.txt
mtree -U -f $to_dir/dir.txt -p $to_dir
OR rsync:
#!/bin/sh
from_dir=/tmp/test
to_dir=/tmp/test-copy
rsync -vraKz --include='*/' --exclude='*' $from_dir $to_dir
