Speed

[pap2003]

Klause Knopper is using a script that makes the original version run faster.
---------------------------------------------------------------------
#!/bin/sh
find / -anewer /KNOPPIX.build/mkisofs.timestamp -not \( -type d -o -path /KNOPPIX.build\* -o -path /tmp\* -o -path /proc/\* -o -path /mnt/\* \) -printf '%p %A@\n' | sort -rn +1 -t' ' | awk -F' ' '{print $1 " " ++i}' > /KNOPPIX.build/mkisofs.sort

echo "/bin/mkdir 10090" >> /KNOPPIX.build/mkisofs.sort
echo "/bin/chown 10080" >> /KNOPPIX.build/mkisofs.sort
echo "/bin/cp 10070" >> /KNOPPIX.build/mkisofs.sort
echo "/bin/ln 10060" >> /KNOPPIX.build/mkisofs.sort
echo "/bin/rm 10050" >> /KNOPPIX.build/mkisofs.sort
echo "/dev/* 20000" >> /KNOPPIX.build/mkisofs.sort
echo "/etc/* 30000" >> /KNOPPIX.build/mkisofs.sort
-----------------------------------------------------------------------

But I can't understand how it works,
What is /KNOPPIX.build/mkisofs.timestamp and /KNOPPIX.build/mkisofs.sort
Has anyone any idea how it works?

Thanks

Its like what you can do when burning any data CD with windows burning apps- optimize the layout of the files so that they can be accessed more quickly. The ones used more often get put in the places on the cd with the fastest access time. Its also like storing data at the beginning of a HDD. The outer tracks of a disk spin at the same rate as the inner tracks, but the outer tracks are larger so more data goes by the reader in the same amount of time.

[pap2003]

Ok, now I know how it works, but how do I use it.
Between witch steps.
is it before
mkisofs -R -U -V "KNOPPIX.net filesystem" -P "KNOPPIX www.knoppix.net" -hide-rr-moved -cache-inodes -no-bak -pad /mnt/hda1/knx/source/KNOPPIX | nice -5 /usr/bin/create_compressed_fs - 65536 > /mnt/hda1/knx/master/KNOPPIX/KNOPPIX

or after that.

I try to run it but I get mkisofs.timestamp no such file or directory.
A little how-to would be nice.
Has anyone used this script and how

[Zyodin]

I am also having trouble getting this to work. I understand what this script is supposed to do but I do not know how to create mkisofs.timestamp and once I get that file, how do I use mkisofs.sort after running the script?

I assume that this script needs to be run prior to creating large KNOPPIX compressed file and creating the .iso, but should it be run while chrooted or not?

If there is anyone out there that uses this script on their remaster please advise.

Thanks!

Can some one write brief instructions on how to use this sort script for sorting so we can actually use it. In addition, where it syas "KNOPPIX.build" in the script, is that the location of your KNOPPIX chrooted environment ? if not than please explain what needs to be in that folder. Also looks like everything in the script points to 2 files -mkisofs.timestamp & mkisofs.sort . What or how are these files suppose to look maybe someone can give an example so we can use the speed sort script. Thank you.

[techfreak]

All right I came across the original scripts that were used by Klaus Knopper to build the original Knoppix CD. These are from April 2003 so they are old but maybe someone can help me modify these so they suit Knoppix 3.4. Here are the scripts:

Attached.

WARNING: THESE SCRIPTS WILL DESTROY YOUR ENTIRE SYSTEM, MAKE YOUR
HARDDISK UNREADABLE, YOUR TV WILL EXPLODE, YOU WILL HAVE 7 YEARS OF BAD
LUCK, YOUR GIRLFRIEND WILL LEAVE YOU, AND THE WORLD AS WE KNOW IT

Seriously, please don't run these scripts without reading them
carefully, understanding what they do and modifying them accordingly.

Can some one write brief instructions on how to use this sort script for sorting so we can actually use it. In addition, where it syas "KNOPPIX.build" in the script, is that the location of your KNOPPIX chrooted environment ?.

Well no it isn't since they do not use chroot to remaster! You must actually boot into your remastering environment. Now I have not yet figured out the sorting scripts either and I also know that it is possible to use only one partition for remastering but I use 2. I am fully aware that there is still much room for improvement in this method. Also notice that I use Kanotix so adjust accordingly for Knoppix.

This is very easy to do and here's how I do it. (Thought about adding this to the wiki but the docs there get hosed up really quickly!!) Anyway........

#Substitue your own drives for /hda11 & /hda12 throughout.
#/hda11 will be the SOURCE direcotory- the directory we install Kanotix to.
#/hda11 is: 1 partition of 3G (or more if you want to make a dvd)
#/hda12 will be the BUILD directory containing the compressed KNOPPIX fs,
# boot.img & final image (kanotix.iso).
#/hda12 is: 1 partition of 1G (more if you're making a dvd).
_______________________________
#BOOT & INSTALL KANOTIX
sudo kanotix-installer
use /dev/hda11 for /
Select 'knoppix' type install!
edit .knofig to install grub to partition
(of course you can install to mbr if you don't wish to boot another OS)

Now you need to clean up. I have a customized version of a script I found somewhere (sorry I forget where) it's at the bottom (maybe by charan??)
ctrl+d (to leave chroot)

Of course you must make adjustments for Knoppix!! Here's the script:

done
}

So hopefully this thread is the start of a very complete and very easy remastering howto. The chroot method is ok if you just want to make some small changes but if you're not running the same kernel you have problems plus other unnecessary issues to deal with.

Of course you can just boot Knoppix, cd KNOPPIX and do cp -a * /mnt/point and then boot into it as well.

Seems we just feed it to mkisofs as Fabianx once told me.
man mkisofs

-sort sort file
Sort file locations on the media. Sorting is controlled by a
file that contains pairs of filenames and sorting offset weight-
ing. If the weighting is higher, the file will be located
closer to the beginning of the media, if the weighting is lower,
the file will be located closer to the end of the media. There
must be only one space or tabs character between the filename
and the weight and the weight must be the last characters on a
line. The filename is taken to include all the characters up to,
but not including the last space or tab character on a line.
This is to allow for space characters to be in, or at the end of
a filename. This option does not sort the order of the file
names that appear in the ISO9660 directory. It sorts the order
in which the file data is written to the CD image - which may be
useful in order to optimize the data layout on a CD. See
README.sort for more details.

The other scripts tidy everything up quite nicely. Simple!

It would be nice if you could add step-by-step instructions to the remastering howto on this website once you have it running.

[Ghandalfar]

you could run your remaster inside user-mode-linux so you wouldn't have to boot. I have yet to find time to write script that would do that.
