In this case, read the section on libc. The flock system call was changed
in 1.3.x, and it breaks with older libc's. Just upgrade to 5.2.18,
recompile any old static bins you might have that were linked against the
old libc and that might call flock (stuff like agetty), and you should be
all set.

PS. Hey Linus, just when can we expect to see that promised ESP-driver in
the kernel? Obviously, I need it, or I'd already know the answer to this
question ;-)
