 and dhcpcd (DHCP client daemon) for IP autoconfig, so you can use identical
disks in different machines!

 There is no Free sh.  It's a symlink to bash on most Linux systems, and
bash2 + necessary libraries won't fit on a single floppy!  ash is commonly
used for install disks and such.  BTW, Solaris has sh, and it is the
crappiest, under-featured shell I've ever seen (e.g. no line editting, like
ash!).  (on Sol 2.6, it is the default shell, even though ksh, which is far
better, is available.)

  good point.  Updates would have to be done on a more fully featured
computer, I think, and new floppies created.  There probably wouldn't be
room for (a recent version of) lynx anyway, unless you stripped out all the
colour support and stuff.  It's a pretty big binary these days:

peter at llama:~$ what lynx
-rwxr-xr-x    1 root     root      1067312 May  1 23:01 /usr/bin/lynx*
/usr/bin/lynx: ELF 32-bit LSB executable, Intel 80386, version 1,
dynamically linked (uses shared libs), stripped

(I'm running Debian potato on this machine.)

#define X(x,y) x##y
