The init script(s) provided in FILESDIR for net-misc/ntp has a license of GPL-2 but GPL-2 isn't within the LICENSE variable of the ebuild(s): files/ntp-client.rc has license line: # Distributed under the terms of the GNU General Public License v2 ... and is used by the following ebuilds: ntp-4.2.4_p7-r1.ebuild:LICENSE="as-is" ntp-4.2.6_p2-r1.ebuild:LICENSE="as-is" ntp-4.2.6_p3.ebuild:LICENSE="as-is" ntp-4.2.6_p3-r1.ebuild:LICENSE="as-is" ntp-4.2.6_p4.ebuild:LICENSE="as-is" ntp-4.2.6_p5.ebuild:LICENSE="as-is" ntp-4.2.6_p5-r1.ebuild:LICENSE="as-is" files/ntpd.rc has license line: # Distributed under the terms of the GNU General Public License v2 ... and is used by the following ebuilds: ntp-4.2.4_p7-r1.ebuild:LICENSE="as-is" ntp-4.2.6_p2-r1.ebuild:LICENSE="as-is" ntp-4.2.6_p3.ebuild:LICENSE="as-is" ntp-4.2.6_p3-r1.ebuild:LICENSE="as-is" ntp-4.2.6_p4.ebuild:LICENSE="as-is" ntp-4.2.6_p5.ebuild:LICENSE="as-is" ntp-4.2.6_p5-r1.ebuild:LICENSE="as-is" There are two options here -- either LICENSE in the ebuilds should be appended with GPL-2 to cover the init script, or the init script should be relicensed so that it is covered by current LICENSE (this one is probably the preferred resolution). See also bug 425702 .
feel free to make any init.d license related change in any base-system ebuild
