*Roger, perhaps this is true, however, it is still a surprise to my
simple mind. I freely admit that these problems are between my ears. I
just don't know how to recover from this failure on my part to grasp the
I think that there are 2 reasonable alternatives:
1. Use the CD as was intended for new users, and boot off of it each time
you want to use Linux/Linrad, and forget installing it to hard disk. You
can save your configuration and a disk image to windows as previously
described, so that you don't lose all of your 'stuff' each time you reboot.
2. Decide to learn all about Linux and become a developer. Then
installing Linux to hard disk makes sense. But then you will definitely
need to learn all about Linux. When the install to hard disk instructions
were given they were in this context:
"Most of this document describes what I did to set up a system so that I
could crank out Knoppix-CD's with Linad and svgalib on them, in case you
want to do that too.
However, first, here is a description of what you need to do to use the
KNOPPIX CD that I made with Linrad and svgalib already on it".
I guess this wasn't clear enough. I should have explicitly said "Stay
away from option #2 above unless you are, or want to be, a developer".
I have commented in previous emails and in several documents the
of which I have posted that the UNIONFS folder is there only when the
RAMDISK system is in play , when the CD boot is used. It is therefore
perfectly logical [and in fact expected] that it will disappear when a
Hard drive installation is performed. And as just stated, this
has been documented previously on this list.
*I have no thought that your CD is defective. As a matter of fact, it is
the only bright spot in my entire Linux/Linrad experience. The simple
fact remains that I do not, even with your explanation, grasp the
concept that what I install from the CD is not what I get when I boot
from the CD.
OK, the line:
" OR, am I stuck until the current W3SZ file is modified to properly
install on HDD?"
sounded to me like it was saying that the disk/file was defective. But I
see now that that is just one way to interpret it. The file is not
defective. It was designed to work when the CD is used to boot into
Linux. When one boots from Hard disk, the file structure is different [no
UNIONFS] and so the file will not work. If one has installed to hard
disk, one is presumably a developer, and doesn't need the script file,
which is there just so new users don't need to know anything about the
file structure on the disk when they boot up using the CD.
There is nothing wrong with the CD that I uploaded in this respect. The
scripts are written for CD boot. They are not written for HD boot. If
wish to boot from HD and use the scripts, simply remove the UNIONFS
portion of the address from the scripts where necessary and all will
The above says, "Remove the /UNIONFS from the addresses that don't work".
If you do that after you have installed to hard disk, all will work. If
you can't find a file you need, just do 'updatedb' and then locate
'filexxx' or whatever and Linux will show you everywhere 'filexxx'
appears. You can use the wildcard '*' where appropriate.
*I feel like I have been learning Linux for centuries. The simple fact
remains that in my simple mind there is no logic to the Linux structure.
This problem is not about lack of effort to learn about Linux, rather it
is about something in my thought process that has not yet come to grips
with the Linux structure and processes. I have a stack of information
that has now grown to well over 2.5 inches thick. I have read every
page several times, and so far it has yet to sink in. This information
includes everything from a 166 page "basic" tutorial on Linux, to all of
the generously offered information from you and others on this
reflector. apparently I must be willing to accept the idea that I must
be confined to the Live CD concept.
I'd suggest re-reading some of what you have read, and trying some
exercises like finding certain filename fragments on the hard drive,
running linrad and other applications from directories other than their
own and seeing what happens, using the 'dir' function from directories
other than the one in which you reside, etc. The only way to 'learn'
linux is to use it, make mistakes, and try to figure out what went wrong
and then correct it.
Taking some time to learn just a little bit about Linux, however
distasteful that may be, will go a long way in helping one to solve
problems as they arise.
I am like that dog chasing the car. Now that I have caught it, I don't
know what to do with it.
1. Using Linrad after booting from the CD.
2. Playing with Linux as above to get more familiar with it.
3. Not bothering to work with Linux installed on the hard drive unless
you want to become a developer.
Let me suggest this as a possibility: is it possible to copy the data
from the Live CD to a HDD and run it as if it were being booted from the
CD? That would preserve the ease of using the Live CD, and provide the
speed gained from a HDD installation.
"sudo knoppix-installer" typed from within Knoppix after booting up from
the CD will install knoppix on a hard drive. Then, I believe, if you are
using the 2005-5-15 version, the
/knuser/linrad directory will contain linrad and you can just go there and
type "./linrad" to run Linrad.
Remember that you need to be a superuser to run Linrad, so type 'su' in
the terminal window before running Linrad.
I just tried the 2005-5-15 CD on another machine, a 3.2 GHz Pentium 4 with
onboard sound and PCI Express Video and two serial ATA drives, and Linrad
runs fine although the screen becomes whited out after one leaves Linrad.
So this Knoppix 3.8.1 CD works fine on this new hardware. But Knoppix
3.8.2 hangs up partway thru the boot process. I haven't had time to
investigate this [and probably won't for a while]. The 3.8.2 does use a
new hardware detection algorithm. It is possible that this doesn't like
the SATA drives. I will at this point stay with the most recent CD
2005-5-15 rather than moving forward to the 3.8.2 version of Knoppix, and
will stay with LInrad-01.34 as well, because the current CD seems to be
The download currently on the website will therefore remain the current
version for the forseeable future.
