Booting error after post-install update [Solved]

hi

Been using Linux for a while, but wanting to learn rather than just use, so decided to give Arch a go, after the review in LinuxMagazine.

Managed to install and boot into it after a few trial and error.

Ran "pacman -Syu"
pacman updated itself, then ran into the hotplug conflict. I took it from This thread that it was safe to accept to remove hotplug.

Ran "pacman -Syu" again 
I then ran into the the error:

error: the following file conflicts were found
grub: /usr/share/grub: exists in filesystem.

Followed This thread and did

'mv' /usr/share/grub to something like /usr/share/grub-backup

.

Ran pacman -Syu again, this time, it ran properly (I think)
Rebooted the computer, ran into  a kernel panic:

UFS: unable to mount root on unknown-block(0,0)

. Followed This thread and  the wiki and edited the instruction on Grub's boot screen to set

root=/dev/hda1 ro

and added

initrd /initrd26.img

to the line uderneath.

this allows me to boot (sort off), but I then get the following error:

/bin/sh: can't access tty; job control turned off

.
From there, I get what seems to be a limited shell (get the "#" sign but not the location I am in such as "root@archbox:#" which I would expect). Here, I am snookered. If I search the wiki for this message, I get one article which refers to Cups and is not relevant to the issue, as far as I can tell, and I do not get any joy from the forum either.
Reinstalling the system is not a problem, but I would rather understand what is happening before I do it, so that I can fix it if the issue reappears, and because it fits into the "learning" purpose of installing this distro.

Could someone guide me on my next step?

Thx
Damien

Change initrd26.img to initrd26-full.img, and you should be able to boot. When you're up and running, have a look at the wiki page on initrd for more info.

Thanks, that did it. Thought I had tired that as well, though, must have been tired and made some typos.....

On a sidenote, it seems that after the install, there was "/dev/discs/disc0" then came the partitions: part1; part2; part3, which is now translated as hda1; hda2; hda3.  I thought partitions started with hda0..  Am I wrong or is the way Arch auto-prepares the hard drive just skips the 0 partition?

No, hda1 is the first partition on your first disc!

Here's an excerpt from the old grub/menu.lst that might help:

# DEVICE NAME CONVERSIONS
#
#  Old /dev    DevFS                    Grub
# -----------------------------------------------
#  /dev/fd0    /dev/floppy/0            (fd0)
#  /dev/hda    /dev/discs/disc0/disc    (hd0)
#  /dev/hdb2   /dev/discs/disc1/part2   (hd1,1)
#  /dev/hda3   /dev/discs/disc0/part3   (hd0,2)

Udev names are the same as "Old /dev" names, btw.
