For files on the disk -that are owned by nobody ( -1 ), they will instead look as if they are owned -by the default ID. The ignore option causes the default ID to override all -IDs on the disk, not just -1. The forget option causes all IDs to be written -to disk as -1, so when the media is later remounted, they will appear to be -owned by whatever default ID it is mounted with at that time. +decimal numeric value and all inodes on that mount will then appear as +belonging to that uid and gid. Mount options also accept the string "forget". +The forget option causes all IDs to be written to disk as -1 which is a way +of UDF standard to indicate that IDs are not supported for these files . -For typical desktop use of removable media, you should set the ID to that -of the interactively logged on user, and also specify both the forget and -ignore options.
