Re: [Bug-ddrescue] Forgot the mapfile.....

[Shahrukh Merchant]

While I discovered ddrescue when I really needed to rescue a disk (for 
which mapfile is of course critical), I now routinely use it to create 
periodic full backups of my hard drive as (mountable) image files, as I 
find it superior for that purpose than the various other disk cloning 
software around. For that use, one really doesn't need a mapfile (I 
create it anyway and check it at the end, to have the nice satisfaction 
of seeing a single line entry covering the entire range of sectors with 
no errors!).

But I guess you could make an argument for creating a 
defaultNNNN.mapfile in the home directory (of the ddrescue execution 
environment, which may well be a non-persistent RAM disk) if no mapfile 
was specified.
