The underlying problem is how to handle a library call from within the NSS/PAM/whatever shared library. This has been discussed in one of the recent threads but it boils down to: 1) Static executables don't normally have any symbols available at runtime so it's difficult for a shared library to resolve symbols using definitions in the executable. 2) It is possible (likely?) that a shared library may reference a symbol that does not exist within the executable. 3) Loading libc.so etc to resolve a symbol means that there may be two distinct (and possibly different) instances of the same object associated with a process. This may create problems where those objects have side-effects. PeterReceived on Mon Nov 24 2003 - 23:18:24 UTC
