Most Redhat based distributions use "chkconfig" for creating links for init-scripts. If your distribution is not, read one of the other paragraphs below.

The replacing lines will be:

sed 's,\(^keytouchinit=\)\(.*\),\1$(bindir)/keytouch-init,' keytouch-init.sh \
  > $(DESTDIR)$(sysconfdir)/init.d/keytouch-init.sh;
chmod +x $(DESTDIR)/etc/init.d/keytouch-init.sh;
