[BusyBox] Busybox inetd wu-ftpd getservbyname

[Yoann Allain]

Thanks for the advice Mike.
I was thinking about using ulibc but I haven't done it for the moment. 
For now I doing latency tests on the system...

Actually, anything linked against glibc using NSS libraries primitives.  You may want to look at other libc  implementations like uLibc if you want to remove the libnss dependency.

>>If you haven't compiled busybox with "internal password and group functions rather than system functions" found under the Login/Password Management Utilities section, chances are you will need libnss_files.so.  glibc 2.x.x uses DLL type access to acces this file using the dlopen() routine.  Binaries that use dlopen will not list these libraries as dependencies when doing an ldd nor will they list it as "NEEDED" when using readelf unless you've added it manually to the ELF header.
