# Go environment - sourced by /etc/profile for interactive login shells.
#
# All Go state lives under /usr/local/share/go (declared as a Docker
# VOLUME). The paths /go, /root/go, /root/.go, /root/.local/share/go and
# /data/go are symlinks to that location, so any of them can be used
# interchangeably and the data persists across container rebuilds when
# the volume is named.
#
# The Go distribution itself lives at /usr/local/go (baked into the image,
# not volumed). Tools installed at build time land in /usr/local/bin.

# Go distribution bin first, then baked tools, then GOPATH/bin last so a
# volume-mounted $GOPATH/bin never shadows baked image tools.
