The permissions are correct, however, the ftpd we're using calls
getcwd, which calls popen("pwd"), which tries to invoke "/bin/sh -c
pwd", and after chroot into ~ftp there is no /bin/sh.
We could use getwd, but it takes no length argument, so we'd have to
check that the SunOS implementation has no buffer overflow problems.
Maybe we can grab the newlib getcwd instead.
Sigh.
For now, yes, just ignore the problem.
