Mmm... Thanks... but it doesn't work :-(

The big problemo is that I don't have a loop.o module... depmod -a ; modprobe
-l gives me
/lib/modules/2.2.17/ipv4/ip_masq_* ( cuseeme, quake... that stuff )

In make menuconfig the loopback device is off, but that's the loopback device
under block devices.. I don't think that has anything to do with the
"noetworking" loopback...

Oh... I found out the problem: kmod reads the location of modprobe from
/proc/sys/kernel/modprobe (I thought), and it tells /sbin/modprobe, while it's
really in /usr/modprobe. So in the next LFS shoud be menthione either
- echo "/usr//sbin/modprobe" > /proc/sys/kernel/modprobe  (this should happen
everytime at boot time, before any other progs
cd /sbin && ln -s ../usr/sbin/modprobe modprobe (needs to be done once, thus is
way simpler!)

modules said I shouls alias net-pf- 3,4 and 6 to "off", I did so with 5&9 too,
it still doesn't work...

indeed... in /lib/modules/2.2.17. I just overlooked it. sorry.

and they add errors!

Everyone calling himself a linux master should have completely read the Bash
man page and all kernel documentation, as a test to prove himself and to free
some bandwith on comp.os.linux.* ( Honestly, I haven't done this all yet )-:
