*** The directory specified for the temporary root environment,
     /var/tmp/temproot, exists.  This can be a security risk if untrusted

   Use 'd' to delete the old /var/tmp/temproot and continue
   Use 't' to select a new temporary root directory
   Use 'e' to exit mergemaster

   Default is to use /var/tmp/temproot as is

How should I deal with this? [Use the existing /var/tmp/temproot] d
