NAME

       uml_moo — merge a COW file with its backing file

SYNOPSIS

       uml_moo [COW file]  [new_backing_file]

DESCRIPTION

       This manual page documents briefly the uml_moo command.

       This  manual  page  was written for the Debian GNU/Linux distribution because the original
       program does not have a manual page.  Instead, it has documentation in  HTML  format;  see
       below.

       uml_moo  is a program to merge a COW (copy-on-write) file with its backing file, and write
       the result to a new backing file.  This can be used periodically  to  update  the  backing
       file with the changes made in the COW file.

       NOTE: you can save a lot of disk space using COW files.  When checking the size of the COW
       file in order to see the gobs of space that you're saving, make sure you use 'ls  -ls'  to
       see  the  actual  disk  consumption  rather  than  the length of the file. The COW file is
       sparse, so the length will be very different from the disk usage.
