Re: ClefOS 7.4 installation (was: RE: Truth/Troth what is the difference?)
That's my understanding of the reason for the /dev/root being missing; there's no root= in the kernel parms. Again, I have the ISO loop-mounted so I can IPL from it in Hercules, and I can find the install.img file, and the generic.ins file points to the install.img file andI don't know what more I have to specify in the kernel parms for it to find that copy, but I'll experiment with that again. So, I used your kernel parms, and it booted much like it has been; the lines that are different in my install log are trivial... setup: Linux is running natively in 64-bit mode cpu: The CPU configuration topology of the machines is: 0 0 0 0 1 8 / 2 My memory setting is 1/4th of yours. The Kernel command line shows as Kernel command line: root=live:http://download.sinenomine.net/cle fos/7/images/install.img ramdisk_siz And that's it for the kernel command; for some reason Hercules doesn't always dump output lines correctly, like, the message about "static device nodes" sometimes comes out as "sta...ce nodes". Don't know what that’s about, but it continues right along, regardless. And the rest of your log and mine match, down to that kernel command. Thanks for the info. I'm still thinking about how I'm going to install it in an LPAR; I'm going to have to burn a DVD to get this ISO to my HMC, which is ok, I just need to make it work here first.

ClefOS 7.4 installation (was: RE: Truth/Troth what is the difference?)
I am installing ClefOS 7.4 to run under Hercules, to make sure what I have to
do before attempting to install it (ClefOS) into an LPAR.
Hercules is running under Centos 6.something on my laptop.
I have the 74base.iso loop-mounted, so it should be loading everything via http
within Hercules.
I have the 74update.iso, if that would work better, but I haven't tried it yet.
I have done a variety of things to make the installation work, and it hasn't so
far. I never get the timeout-starting messages Frank gets, but I always seem to
get down to that message about /dev/root not existing.
Google shows a number of these occurrences in the past, mostly because the
ramdisk didn't get started/created properly. I have increased the memory that
Hercules specifies for this guy, but I keep getting...
>Warning: /dev/root does not exist
I figured it was just me. I think I have a problem with my kernel parms, based
