Certain avoidable problems arise when one attempts to use a non-root user to do backups.


For instance, see this earlier bug report I submitted:

https://savannah.nongnu.org/bugs/index.php?27729

This arises because non-root users can not read root-read-only symlink targets on the local filesystem. If rdiff-backup is running as non-root, it should not attempt to read local filesystem symlink targets.



Another case is when I back up files that are mode 000 (non-read/write by anyone). Root would be able to read and remove these files, but since I am running as non-root, rdiff-backup is unable to alter these files once they have been created. When running as non-root, such files should instead be at least readable by the non-root user.




There may be other applicable cases as well. Thus I propose a new flag when invoking rdiff-backup to do a backup: --unprivileged-user. This signals to rdiff-backup that special handling will be required, since it will not be able to run with complete read-write privileges on the local filesystem.
