    Well, there is at least one issue with this.  I'm not sure the 
option is
    general enough.  e.g. perhaps it should not avoid symlinks.  I'd 
use
    stat() rather then lstat() at the very least.
the main purpose of this is to avoid symlinked directories, but I 
thought going a little bit more general and ignoring anything 
non-regular would be better in the end.

    Grep isn't realliy the best utility to search an entire hierarchy.
    I would use a comnation of find with the -exec option to write
    a search script.
For sophisticated stuff yes, but I just wanted a quick hack to "just 
grep -Or /sys $foo"
