# Used to create a copy of the a directory tree that has links for all
# non- directories (except those named RCS or SCCS).  If you are
# building the distribution on more than one machine, you should use
# this script.
#
# If your master sources are located in /usr/local/src/X and you would like
# your link tree to be in /usr/local/src/new-X, do the following:
#
#         %  mkdir /usr/local/src/new-X
#        %  cd /usr/local/src/new-X
#         %  lndir ../X

BTW:
kernel的编译选项:
make O=/home/your/linux-o
将编译的后目标文件放在你想要的目录.

这样不会破坏源代码目录.

这两种方法都很好.
