i have 3 builds (deb packages), one from 28.sep, second from 4.oct and third from 7.oct

when i uninstalled vpp with:
sudo dpkg --purge vpp vpp-dbg vpp-dev vpp-dpdk-dev vpp-dpdk-dkms vpp-lib vpp-plugins
and have installed second or third build, vpp could not start because huge pages config file is here:

• Applying /usr/lib/sysctl.d/80-vpp.conf ...
  instead of /etc as was in first build

if i check hugepages (after reboot), they are not set:
vagrant@localhost:~$ cat /proc/meminfo | grep Huge
AnonHugePages: 0 kB
HugePages_Total: 0
HugePages_Free: 0
HugePages_Rsvd: 0
HugePages_Surp: 0
Hugepagesize: 2048 kB

and vpp is not starting:
Oct 7 05:07:39 localhost kernel: [ 4278.641325] init: vpp main process ended, respawning
Oct 7 05:07:39 localhost vpp[1519]: dpdk_config: not enough free huge pages
Oct 7 05:07:39 localhost kernel: [ 4278.670617] init: vpp main process ended, respawning
Oct 7 05:07:39 localhost vpp[1526]: dpdk_config: not enough free huge pages
Oct 7 05:07:39 localhost kernel: [ 4278.700084] init: vpp respawning too fast, stopped

also inside deb file, path was changed:
rw-rr- root/root 548 2016-08-24 23:58 ./usr/lib/sysctl.d/80-vpp.conf

workaround for this is just reinstalling old one (first) build with some newer build (without uninstalling previous), then path is not changed to /usr/lib and file stays in /etc/sysctl.d:

• Applying /etc/sysctl.d/80-vpp.conf ...
