You want to see some fireworks?  At least at one time, it was possible to use
a file system debugger that's all too trusting of hexadecimal input and create
a directory entry of '../'. Let's just say that fs/namei.c was also far too trusting,
and fsck was more than happy to make *different* errors than the kernel was....

Don't forget ESC, CR, LF, backticks, forward ticks, semicolons, and pretty much
anything else that will give a shell indigestion. SQL isn't the only thing prone to
