Subject: isc-dhcp: use modzone not addzone so in-addr.arpa works
X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=27f55cdbda2259bcd8ab3f0b7c56aca12931689f;p=feed%2Fpackages.git

isc-dhcp: use modzone not addzone so in-addr.arpa works

Updates to in-addr.arpa are being rejected with:

update failed: REFUSED

because we create an empty zone, and then try to add it again
when it already exists.  So use modzone instead to update it.
