@cindex deduplication
Disable automatic file ``deduplication'' in the store.
By default, files added to the store are automatically ``deduplicated'':
if a newly added file is identical as another one found in the store,
the daemon makes the new file a hard link to the other file. This
slightly increases the input/output load at the end of a build process.
This option disables this.

noticeably reduce disk usage, at the expense of slightly increasde
input/output load at the end of a build process. This option disables
this optimization.
