BusyBox, uClinux, telnetd and shared memory

[Ian Oliver]

Hi,

I hope someone can help me with a quick question, or at least tell me 
where to go to read more on the subject.

I'm pretty familiar with MMU Linux and have read a fair bit about how 
uClinux differs. But I'm still not sure about the best approach regards 
using daemons such as telnetd with BusyBox.

If I launch telnetd, I guess that BB does a vfork and then execs BB 
again to run the telnetd applet. Will uClinux share the code pages 
involved (which are loaded from a cramfs) or am I best minimising 
memory usage by building a separate BB executable that contains only 
the telnetd applet?

Ditto for the shell that telnetd will launch - build into a single copy 
of BB or have a separate executable?

Thanks

Ian
