Comment 4 for bug 1639095

I happened to install arch linux 20170301 on a virtualbox then install snapd with "pacman -S snapd".
The /etc/profile.d/apps-bin-path.sh on my side is:

# Expand the $PATH to include /snaps/bin which is what snappy applications
# use
PATH=$PATH:/snap/bin

if [ -z "$XDG_DATA_DIRS" ]; then
    XDG_DATA_DIRS=/usr/local/share/:/usr/share/:/var/lib/snapd/desktop
else
    XDG_DATA_DIRS="$XDG_DATA_DIRS":/var/lib/snapd/desktop
fi
export XDG_DATA_DIRS
