snap-discard-ns - internal tool for discarding preserved namespaces of snappy applications
snap-discard-ns [--from-snap-confine] SNAP_INSTANCE_NAME
The snap-discard-ns is a program used internally by snapd to discard a preserved mount namespace of a particular snap.
The --from-snap-confine option is used internally by snap-confine to tell snap-discard-ns that it is invoked from snap-confine and can disable locking.
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.
snap-discard-ns uses the following files:
/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.
