[Fedora-xen] inittab corrupted/serial console broken on Xen-ified kernel?

[Evan Lavelle]

[this is a message that I sent to xen-users yesterday, but I guess this 
list may be better - this looks like a problem either in Xen, or in the 
packaging of 2.6.21-2952.fc8xen].

I've just installed Fedora 8 / xen-2.6.21 on a headless server, but I
can't get a serial console login on the Xen version of the kernel.

1 - If I boot into 2.6.23.8-63.fc8, the serial console login works as
expected

2 - If I boot into 2.6.21-2952.fc8xen instead, I get all the expected
serial output up to the end of the boot process, but no login.

When I boot into the xen kernel, inittab is modified, and the
modification removes the agetty on ttyS0. If I compare the old inittab
with the new inittab, I get:

46,47c46
< # co:2345:respawn:/sbin/agetty xvc0 96 9600 vt100-nav
< co:12345:respawn:/sbin/agetty ttyS0 115200 vt100
---
 >  co:2345:respawn:/sbin/agetty xvc0 96 9600 vt100-nav

In other words, a commented entry was uncommented, and the following
line was deleted, which explains why I can't log in. This is so bizarre
that it almost looks like it was done on purpose (was it ? :))

Anyone seen this? Any ideas?

Thanks -

Evan
