upp not really, once a program has a file open you can move the file around or
delete it and it will still be available as the kernel still provides that to
the process that opened it. It is not until the file handle is closed that the
file with no longer be in the place or the file will dissapear from that
path. Once a file is opened the path is not relevant. (this is a unix thing,
all unix variants supposedly do it this way)

But yes a reboot will really be easier than messing around with life
filesystem and daemons for something like this.
