Between (1) and (3) I believe it's mainly a matter of whether you think
your fixes to the Makefile can be integrated upstream into a new
release or not. If your Makefile changes can be integrated upstream and
a new release is made, we can update Buildroot to use this new release,
drop the patch, and everything is nice. On the other hand, if the
upstream is more or less dead (which the very old version number seems
to indicate), then the chances of having the patch accepted and a new
release published is rather small. In that case, doing a manual
AICCU_INSTALL_TARGET_CMDS and AICCU_INSTALL_INIT_SYSV is probably
better.

Network is S40network. ntp is installed at S49ntp. So I guess something
>= 50 should be fine.

You don't need to set explicit permissions if you use the
AICCU_INSTALL_INIT_SYSV method since you do an $(INSTALL) -m 0755.

Thanks a lot!
