summary: Check that snap apps and services can write to writable areas.
details: |
The confinement system allows snap applications to write to four locations:
snap data specific to the current revision, snap data common across
revisions, snap user data specific to the current revision and lastly snap
user data common across revisions.
environment:
# Ensure that running purely from the deb (without re-exec) works
# correctly
SNAP_REEXEC/reexec0: 0
SNAP_REEXEC/reexec1: 1
prepare: |
if [ "$SNAP_REEXEC" = "0" ] && tests.info is-snapd-from-archive; then
tests.exec skip-test "No need to test when the snapd pkg is from the repository and reexec is disabled" && exit 0
fi
snap pack data-writer
SNAP_MOUNT_DIR="$(os.paths snap-mount-dir)"
if [ "$SNAP_REEXEC" = "1" ] && [ "$SNAP_MOUNT_DIR" != "/snap" ] && [ ! -L /snap ]; then
# reexec expects to find the snapd snap under /snap, enable it to do so
# on distros using /var/lib/snapd/snap
ln -sf "$SNAP_MOUNT_DIR" /snap
tests.cleanup defer rm -f /snap
