newmount
Dependency-free ctypes bindings for the Linux mount API: the classic mount(2)/umount2(2) calls, and the new mount API (kernel 5.2+) built on fsopen, fsconfig, fsmount, open_tree, move_mount, fspick and mount_setattr.
Requires Python 3.10+ and Linux. Mounting needs CAP_SYS_ADMIN; an
unprivileged process gets there inside a user+mount namespace
(unshare -Urm).
Install
pip install newmount
Example: classic bind mount
import newmount
# bind recursively, then remount read-only
newmount.bind("/srv/data", "/mnt/data", readonly=True)
Example: clone, reconfigure and attach with the new API
import newmount
# clone the tree, flip the clone read-only, attach it
with newmount.open_tree_clone("/srv/data") as tree:
tree.apply_attrs(set=newmount.MOUNT_ATTR_RDONLY)
tree.attach("/mnt/data")
# or build a fresh filesystem from scratch
with newmount.FsContext("tmpfs") as ctx:
ctx.set("size", "16m")
ctx.create()
with ctx.mount() as mnt:
mnt.attach("/mnt/scratch")
