+ help
+ When using flat shared libraries, every library has a unique
+ system-wide identifier. Identifier 0 is reserved for
+ executables and true shared libraries have identifiers
+ starting at 1. The maximum shared library identifier is
+ determined by the kernel and is usually 3. Shared library
+ N must be available on the target system as "/lib/libN.so".
+
+ When a shared C library is used, it usually has identifier 1,
+ but you can use this option to select a different identifier
+ if you need to.

- The kernel source you use to compile with should be the same as the
- Linux kernel you run your apps on. uClibc doesn't even try to achieve binary
- compatibility across kernel versions. So don't expect, for example, uClibc
- compiled with Linux kernel 2.0.x to implement lchown properly, since 2.0.x
- can't do that. Similarly, if you compile uClibc vs Linux 2.4.x kernel headers,
- but then run on Linux 2.0.x, lchown will be compiled into uClibc, but won't
- work at all. You have been warned.
