Crate bootc_internal_mount 

Helpers for interacting with mountpoints

Modules

tempmount

Temporary mount management with automatic cleanup.

Structs

Filesystem

Deserialized information about a mounted filesystem from findmnt.

Findmnt

Deserialized output of findmnt --json.

Constants

PID1

Well known identifier for pid 1

Functions

bind_mount_from_pidns

Create a bind mount from the mount namespace of the target pid into our mount namespace.

ensure_mirrored_host_mount

If the target path is not already mirrored from the host (e.g. via -v /dev:/dev) then recursively mount it.

find_mount_target_by_source

Find the mount target of a given source device in the current mount namespace. Returns Ok(None) if the device is not mounted.

find_source_mount_target 🔒

findmnt_filesystem 🔒

inspect_filesystem

Inspect a target which must be a mountpoint root - it is an error if the target is not the mount root.

inspect_filesystem_by_uuid

Inspect a filesystem by partition UUID

inspect_filesystem_of_dir

Inspect a target which must be a mountpoint root - it is an error if the target is not the mount root.

is_mounted_in_pid1_mountns

Check if a specified device contains an already mounted filesystem in the root mount namespace.

is_same_as_host

If the fsid of the passed path matches the fsid of the same path rooted at /proc/1/root, it is assumed that these are indeed the same mounted filesystem between container and host. Path should be absolute.

is_source_mounted

Recursively check a given filesystem to see if it contains an already mounted source.

mount

Mount a device to the target path.

mount_typed

Mount a device with an explicit filesystem type.

open_tree_from_pidns

Given a pid, enter its mount namespace and acquire a file descriptor for a mount from that namespace.

pid1_mounts 🔒

Return the list of mounts visible in pid 1’s mount namespace, as reported by findmnt.

run_findmnt

Run findmnt with JSON output and parse the result.
