    16  SYNOPSIS
    17  ========
    18  
    19  	snap-discard-ns [--from-snap-confine] SNAP_INSTANCE_NAME
    20  
    21  DESCRIPTION
    22  ===========
    23  
    24  The `snap-discard-ns` is a program used internally by `snapd` to discard a preserved
    25  mount namespace of a particular snap.
    26  
    27  OPTIONS
    28  =======
    29  
    30  The --from-snap-confine option is used internally by snap-confine to tell
    31  snap-discard-ns that it is invoked from snap-confine and can disable locking.
    32  
    33  ENVIRONMENT
    34  ===========
    35  
    36  `snap-discard-ns` responds to the following environment variables
    37  
    38  `SNAP_CONFINE_DEBUG`:
    39  	When defined the program will print additional diagnostic information about
    40  	the actions being performed. All the output goes to stderr.
    41  
    42  FILES
    43  =====
    44  
    45  `snap-discard-ns` uses the following files:
    46  
    47  `/run/snapd/ns/$SNAP_INSTNACE_NAME.mnt`:
    48  `/run/snapd/ns/$SNAP_INSTNACE_NAME.*.mnt`:
    49  
    50      The preserved mount namespace that is unmounted and removed by
    51      `snap-discard-ns`. The second form is for the per-user mount namespace.
    52  
    53  `/run/snapd/ns/snap.$SNAP_INSTNACE_NAME.fstab`:
    54  `/run/snapd/ns/snap.$SNAP_INSTNACE_NAME.*.user-fstab`:
    55  
    56      The current mount profile of a preserved mount namespace that is removed
    57      by `snap-discard-ns`.
