um_fsalias(1) define a file system type alias


um_fsalias fsalias [ full_filesystem_type ]


This command is used to define a short alias for a full qualified view-os file system type.

For example
um_fsalias ext2 umfuseext2
defines ext2 as a short alias for umfuseext2. ext2 can then be used in a mount command instead of the full name umfuseext2.

Further definitions of the same alias re-define the alias by overwriting previous mappings. If full_filesystem_type is omitted, the command deletes any previous definition of the alias.
