Sometime ago I made a floppy linux that had mc on it:

This calling of gethostbyname() was a problem for me, because I needed
to include libnss libraries on the floppy which had limited space, but
I didn't really ever need to resolve a host name (the networking was
only IP address based.)  As I remember, I believe mc did not directly
link to the library, but loaded it when you needed it, thus tricking
me into thinking it didn't need that library because that library
wasn't listed in the output of "ldd /usr/bin/mc".

I considered changing the midnight commander code at the time but
managed to squeeze everything on a floppy in the end.

Perhaps in a future version of my floppy I might change mc to not call
gethostbyname() if it can't find that library; if so I will submit a
patch.  However, it works great now and I am very appreciative to all
the programmers who have worked in midnight commander.
