Environment

snap-discard-ns responds to the following environment variables

SNAP_CONFINE_DEBUG:

When defined the program will print additional diagnostic information about the actions being performed. All the output goes to stderr.

/run/snapd/ns/$SNAP_INSTNACE_NAME.mnt: /run/snapd/ns/$SNAP_INSTNACE_NAME.*.mnt:

The preserved mount namespace that is unmounted and removed by snap-discard-ns. The second form is for the per-user mount namespace.

/run/snapd/ns/snap.$SNAP_INSTNACE_NAME.fstab: /run/snapd/ns/snap.$SNAP_INSTNACE_NAME.*.user-fstab:

The current mount profile of a preserved mount namespace that is removed by snap-discard-ns.
