[Q9] ``Why does getlogin() always return NULL on my Linux box?''
[A9] {UD} The GNU C library has a format for the UTMP and WTMP file
which differs from what your system currently has. It was extended to
fulfill the needs of the next years when IPv6 is introduced. So the
record size is different, fields might have a different position and
so reading the files written by functions from the one library cannot
be read by functions from the other library. Sorry, but this is what
a major release is for. It's better to have a cut now than having no
means to support the new techniques later.

know of any falling under LGPL and where the author is willing to
contribute it to the FSF.

bootparams, netgroup, publickey, automount, aliases databases.
The functions should be embedded in the nss scheme. This is not
hard and not all services must be supported at once.
