# we should put "nix:/nix:ro but it is not supported by
# drone-runner-docker because the dependency envconfig does
# not support having two colons (:) in the same stanza.
# Without the RO flag (or using docker userns), build isolation
# is broken.

# https://github.com/kelseyhightower/envconfig/pull/153
#
# A workaround for isolation is to configure docker with a userns,
# so even if the folder is writable to root, it is not to any non
# privileged docker daemon ran by drone!
