Mgnokiidev

From GnokiiWiki

Does mgnokiidev need to be suid root?

Yes. gnokiid needs to create a symbolic link in the /dev directory. mgnokiidev is the program which does this and hence it must be suid root so it can write to the directory. mgnokiidev is executable only for gnokii group members (and root) so it presents minimal security risk.

Be sure that you don't use a version of gnokii older than 0.3.5 if you want to install mkgnokiidev suid root and give the access for execution for untrusted users. Earlier versions had security problems and allowed people to write to an arbitrary file.
