Hello.

I've just been looking at the FSEXT hooks code. I noticed that symlinks are
not handled consistently. Should the symlink be resolved, before calling a
function that takes a path name? For instance compare
src/libc/ansi/stdio/remove.c and src/libc/posix/sys/stat/lstat.c. lstat.c
passes the FSEXT the resolved name. remove.c passes the FSEXT the original
name. I haven't looked at any other cases, but I think the FSEXT docs should
be more clear on what kind of filename an FSEXT can expect to have passed into
it.

Actually, I have another question. How do we remove symlinks using libc?
According to the unlink man page on RedHat Linux 6.2 unlink() should remove a
symlink. But looking at the code for remove (and hence unlink) in our libc, it
looks like it will always remove the target file. I think this is a bug.

Thanks, bye, Rich =]
