update_merge
|

is like update but does not delete the found file if it is

missing on disk. It may be run several times and records

already been seen by one of the update_merge runs. Finally,

a -find run with action "rm_merge" may remove all files that

saw no counterpart on disk.
|

Up to the next "rm_merge" or "clear_merge" all newly inserted
|
||||
files will get marked as having a disk counterpart.
|

rm
|
||||
removes the found iso_rr_path from the image if it is not a
|
||||
directory with files in it. I.e. this "rm" includes "rmdir".
|

rm_r
|
||||
removes the found iso_rr_path from the image, including whole

directory trees.

rm_merge

removes the found iso_rr_path if it was visited by one or
