And to point directly to the slirp program instead of its folder (which is understood by many as the *path* for anything, not the things themselves, with full path) is news for me, and something that should be pointed in the docs. I think many others will understand it as I did before you said this. Now there is a few lines about slirt and ETH0: === [autodetect SLIP/CSLIP, MTU 1500, MRU 1500, 115200 baud] SLiRP Ready ...

I have downloaded, compiled and installed it. And as detailed in the other message, now I'm stuck on how to use it to run with UML. If Qemu did this, why not doing it with UML too?
