Post-OOPS Network connectivity probs
The story so far .. I received a 'kernel panic' message
while compiling dependencies for 'Scribes' and was not able to reboot
sucessfully. When trying to do so I received error messages to do with ./etc/rc*.d scripts ..

livecd / # /usr/sbin/mkinitrd -o /boot/initrd-2.6.5 2.6.5custom
/usr/sbin/mkinitrd: /etc/mkinitrd/mkinitrd.conf: Configuration file not
found
.. so I read the man page and set up the conf file - but then other
mkinitrd files were missing.
-----------------------------------------------------------------------------------------
I had 2.4.25 and 2.6.5 aboard and had unpacked 2.6.14 prior to compiling it.
When trying ...
mkinitrd /boot/initrd2.6.5
2.6.5custom
I found that /boot/vmlinuz-2.6.5 did not exist.
Tux:~# mkinitrd /boot/initrd-2.6.5 -o 2.6.5custom
/usr/sbin/mkinitrd: /boot/initrd-2.6.5 is not a valid kernel version
I could not see
2.6.5 or 2.4.14 vmlinuz or linuz images on the system.
Symlinks remained in / or /boot but I could not find the actual files ..
unless I am missing something.
I could not find either 2.4.25 or 2.6.5 kernels.
I had the Gentoo-based SystemRescue CD and downloaded and burnt the Gentoo LiveCD, hoping for more features..
I kept trying mkinitrd but kept getting caught with various error messages.
I came to the conclusion that I had to recompile the kernel, but since I
had already unpacked the latest kernel - 2.6.14 - in
/home/adam I decided to proceed with that with the file system mounted
on the Gentoo LiveCD.
After menuconfig I successfully did
make bzImage
and
make modules
but had problems with 'make modules_install',
livecd linux-2.6.14 # make modules_install
mkdir: cannot create directory '/lib/modules/2.6.14': Read-only file system
make: *** [ _modinst_ ] Error 1
.. which I attributed to its using the CD fs.
On reading Linus' kernel release notes I thought of the possibility of
bypassing this via
root@cdimage /home/adam/linux-2.6.14/arch/i386/boot cp bzImage
/boot/vmlinuz-2.6.14
and re-running LiLo
before doing 'modules make_install' from within my own fs
I asked on #gentoo whether this was possible without breaking anything -
'RiverRat' assured me it was.
After a bit of fiddling with /etc/lilo.conf I finally manged to boot
into my own drive
Finally,
Tux: /home/adam/linux-2.6.14# make modules_install
if [ -r System.map -a -x /sbin/depmod ] ; then /sbin/depmod -ae -F
System.map 2.6.14; fi
Tux: /lib/modules# ls
0.0.0 2.4.18-bf2.4 2.4.25-1-686 2.6.14 2.6.5-1-686
Tux: /lib/modules/2.6.14# ls
build modules.ccwmap modules.inputmap modules.seriomap source
modules.dep modules.isapnpmap modules.symbols
kernel modules.alias modules.ieee1394map modules.pcimap modules.usbmap
I could boot into WinXP and
2.6.14 at will
in text mode (init 1), although I had to mount partitions
manually and
had no access to the internet preventing a dist-upgrade
I had correctly AFAIK set up /etc/init.d/network
I later found I could change runlevels successfully via
/sbin/telinit 5
.. X and GDM came up normally but after logging in I found that GNOME
terminal would not give me a cursor with the message "There was an error
creating the child process for this terminal" .. I rebooted in sawfish
and other sessions and found no cursor
on other terminals (eg. Xterm).
There was still no connectivity ..
"Failed to run network-admin as root.
Failed to fork new process: No such file or directory."
On reboot, it hung (timed out) again at
"INIT: Entering runlevel 5
Starting system log daemon: syslogd"
'nano /etc/rcS.d/README' gave me

Having got as far as the GUI gives me grounds for optimism but at the moment I'm at a bit of a loss,
Apt and Mutt both work and enable me to use init 3 (which always takes me to the GUI),
but do not connect preventing a dist-upgrade.
I'd be grateful for any constructive advice.
