Quick start

from unmount_image import umount_image

umount_image('/dev/loop0', mount_point='/run/media/user/IMG')

API

• umount_image(device, mount_point=None, strategy=UNMOUNT_RETRY_THEN_LAZY) — unmount + detach
• detach_image(device) — detach only (non-blocking)
• umount_inner(device) — unmount only, used by the mount-image orchestrator
• detach_inner(device) — detach only, used by the mount-image orchestrator

Unmount strategies

Strategy	Pipeline
UNMOUNT_FAIL_FAST	normal unmount
UNMOUNT_RETRY	normal unmount, retry 3x
UNMOUNT_FORCE	normal → --force
UNMOUNT_LAZY	normal → umount -l
UNMOUNT_FORCE_THEN_LAZY	normal → force → lazy
UNMOUNT_RETRY_THEN_LAZY (default)	retry 3x → lazy

Custom strategies

from unmount_image import umount_image, compose, retry, _unmount_normal, _unmount_force

strategy = compose(retry(_unmount_normal, attempts=5), _unmount_force)
umount_image('/dev/loop0', strategy=strategy)
