[parisc-linux] opening initial console

Well good news and bad news. We've gotten a linux kernal to boot over a network using rbootd and bootp. However just after the root is mounted we get the following message:

NFS: Mounted root (nfs filesystem) readonly.
Warning: unable to open an initial console.
Kernel panic: no int found. Try passing init= option to kernel.

Anyone run into this problem or know how to fix it.

Sounds like you have tried to boot a kernel over the network, and
have it mount a root file system also over the network.  The problem
is likely to be that the kernel failed to find any useful files on
the file system it mounted - no /dev/tty*, no /sbin/init, etc.
Could be access permisions problems.  Try mounting the fs from some
other system and check things look ok.

If you grab the 0.9.1 ISO and boot the lifimage from that, the
lifimage contains 32 and 64 bit kernels, and a ramdisk.  It should
boot and mount root from the ramdisk (not from nfs).

I'm confused about booting from a lifimage. How do we go about this. Note:
we are unbale to install via CDROM because of harware issues so we are
relying on a network install.

P.S. Thanks for all your help so far. We need all we can get.

palo can take a kernel image and wrap stuff round it to make a bootable
image.  That is called a lifimage.  You managed to boot from the
network, so you must have booted a lifimage format file.  You must
have put that lifimage somewhere that bootp/rbootd could find it
when asked by your parisc box.  On the CD is a file called lifimage,
in dists/sid/main/disks-hppa/current/lifimage (or similar).  Simply
copy that file to your bootp server, placing it and naming it as
you did for whatever you booted last time.  Then tell your parisc
box to boot from the network.  Don't interact with the IPL to modify
any kernel boot parameters - it should all "just work".

You should get the installer release notes page displayed, hit return
and you are in to the main installer menu.

Once you have the system installed and using palo to boot from disk,
palo uses plain kernel image files, not lifimages.  Those live in
/boot/vmlinuz or similar, and should be set up for you during the
install.

Hope that helps, ask again if not.
