29 If provided fsck will try to mirror missing files from this location.
30 For remote locations requiring authentication you may need to set the
31 environment variables USER and RSYNC_PASSWORD as well.
39 Consider all answers to asked questions to be I<yes>.
45 Compares disk contents with index contents and gathers files missing
46 on local disk and files missing in local index.
48 If remoteroot is given missing files are fetched from remote.
50 Files on the local disk that have no counterpart in the index are
51 considered obsolete and the user is asked for each file if the file
52 should be deleted. And if the user confirms it will be deleted.
56 There is a race condition when the tree or the index is manipulated
57 while we are running. This implies that the result is only then 100%
58 correct when disk and index are not changed while we are running.
60 There should be an option to declare the files on disk authoritative
61 so that they are added to the index.
