minicom: there is no global configuration file /etc/minirc.dfl
Ask your sysadm to create one (with minicom -s).
[lcamtuf@nimue lcamtuf]$ ls -l foo

Any file can be created anywhere with uucp privledges - it will
follow symlinks. Not nice on systems running uucp services.

To round out the distribution status...
Debian/GNU Linux does not install minicom set[ug]id, and is not
vulnerable... verified on 2.1 (slink), 2.2 (potato), and "woody".
