# 2019-05-30: It's interesting that http://box.lan/admin and everything seems
# to work even without php{{ php_version }}-sqlite3 as confirmed on Ubuntu
# 16.04 (SEE PR #1697).  And likely all others?  @tim-moody writes "I think
# we decided that because sqlite3 and php are part of the base install the
# connector should be too."
#
# We might *try* deprecating this here as we transition beyond {raspbian-9,
# debian-9, ubuntu-18} in coming months to verify that roles/osm-vector-maps
# is the only role that needs it?
