snap-discard-ns - Man Page
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.
