Subject: use of tar in make install rules
Date: Fri, 11 May 2012 15:30:02 -0400 [thread overview]
Message-ID: <ikipg2plc5.fsf@fencepost.gnu.org> (raw)
To install a directory and all its contents (eg lisp), the Emacs Makefile uses:
(cd $${dir}; tar -chf - . ) | \
(cd $${dest}; umask 022; tar -xvf - && cat > /dev/null)
Why does it use tar, as opposed to "cp -R"?
Please don't tell me that cp -R isn't portable...
(There are no symbolic links or device files involved.)
