[Kea-users] DHCPv6: Option 18 and lease storage

[perl-list]

In Kea DHCPv6, I noticed that option 18 "interface-id" is not stored in the lease6 table in mysql.  There isn't a column for it.  Is it possible to include option 18 in the "logging" options if it isn't to be stored with the leases?  With debug on I can see it is received:

relay[0]: msg-type=12(RELAY_FORWARD), hop-count=0,
link-address=2001:0:2:8::1, peer-address=fe80::3d53:b879:121:1725, 3 option(s)
type=00018, len=00011: 47:69:30:2f:30:2f:31:2e:32:34:30
type=00037, len=00022: 9 (uint32) 0200010000F0000A0003000100C1B1EC26D0 (binary)
type=00079, len=00008: 00:01:00:1c:42:bd:c3:6c

Just asking as we use the interface-id to identify subscribers in ISC DHCP and were hoping that was possible in Kea as well.
