It took some trouble -- as of now I only have emerge working in the chroot
from Debian -- but after installing lvm2 it is not cheerfully recognising
all the LVM paritions at boot.
Now for the next problem. emerge doesn't work because the net connexion
is down. Presulably it would be OK if I had a local repository, but iI
don't.
If I ping my internet gateway machine, 172.25.1.1. it tells me
PING 172.25.1.1 (172.25.1.1) 56(84) bytes of data.
--- 172.25.1.1 ping statistics ---
3 packets transmitted, 0 received, 100% packet loss, time 2003ms
whereas when I do the same from Debian,
PING 172.25.1.1 (172.25.1.1) 56(84) bytes of data.
64 bytes from 172.25.1.1: icmp_seq=1 ttl=255 time=0.811 ms
64 bytes from 172.25.1.1: icmp_seq=2 ttl=255 time=0.364 ms
--- 172.25.1.1 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 999ms
rtt min/avg/max/mdev = 0.364/0.587/0.811/0.224 ms
Here's the routing table, obtained with route -n
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.25.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 172.25.1.1 0.0.0.0 UG 0 0 0 eth0
And the same from Debian:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
172.25.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
0.0.0.0 172.25.1.1 0.0.0.0 UG 0 0 0 eth1
Except for lo (which I can wonder about anon) the most striking difference
is that gentoo uses eth0; whereas Debian uses eth1.
Now as far as I know, there's only one ethernet interface on this machine.
But I could be wrong. I do know that there's just one place to plug the
cable into the back.
Running ifconfig to find out more, especially to see if the MAC addresses
are different:
On gentoo:

and on Debian:

Now that's a surprise. Quite sone difference! Debian gives ma an
ordinary 48-bit hardware address. Gentoo gives a 128-bit hardware
address! And the bits of the 48-bit address aren't even recognisable
in the 128-bit address. Now I understand that hardware addresses have been
getting longer, but O haven't been adding ethernet chips to this machine
since I bought it, so they should all be of the same vintage.
What gives?

Only one ethernet controllser visible. Ans except for a different IRQ,
it's remarkably similar to what Debian says:
......
00:04.0 Ethernet controller: nVidia Corporation nForce2 Ethernet Controller

Evidently something is still wrong. How do I begin to diagnose this?
