NAME

       snap-discard-ns - internal tool for discarding preserved namespaces of snappy applications

SYNOPSIS

          snap-discard-ns [--snap-already-locked|--from-snap-confine] SNAP_INSTANCE_NAME

DESCRIPTION

       The  snap-discard-ns  is  a  program used internally by snapd to discard a preserved mount namespace of a
       particular snap.

OPTIONS

       The --snap-already-locked is used  to  indicate  that  the  snap  lock  has  already  been  taken,  which
       snap-discard-ns  verifies  internally.  The --from-snap-confine option is an alias for this option but is
       used only internally when calling snap-discard-ns from snap-confine.

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.

FILES

       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.
