Another problem that comes to mind is the "Too many levels
of symbolic links" errors. If a symbolic link is added at
the beginning of a system path are we increasing the risk
that this error will be triggered?
$ grep MAX_NESTED_LINKS linux/namei.h
enum { MAX_NESTED_LINKS = 8 };
char *saved_names[MAX_NESTED_LINKS + 1];
