summary: Checks for parallel installation interfering with non-parallel snaps
details: |
Make sure parallel instances do not interfere with other snaps. In particular,
parallel instances create a recursive bind mount of $SNAP_MOUNT_DIR. This
should not prevent snaps from being unmounted when removed.
prepare: |
case "$SPREAD_SYSTEM" in
fedora-*|arch-*|centos-*)
# although classic snaps do not work out of the box on fedora,
# we still want to verify if the basics do work if the user
# symlinks /snap to $SNAP_MOUNT_DIR themselves
SNAP_MOUNT_DIR="$(os.paths snap-mount-dir)"
