Knoppix 7.0 Same procedure as every year!

[ruymbeke]

Hello,
I finally got my hands on the German version of the Knoppix 7.0 DVD
which successfully passes the "knoppix testcd" test, and has the following md5:
300586ae0d536b2522494c82d845534b *knoppix_7.0.iso
For those who may be interested in correcting the few corrupted (and not critical)
files included within the English version of the /KNOPPIX/KNOPPIX cloop file
please find below the link to the correct data extracted from the German DVD:
http://s94002264.onlinehome.us/grub/...PIX_70_fix.tgz
and below the md5 of the correct files included in the above file:
d6aafd5451b9b1700b5bcb393948b92c KNOPPIX/usr/bin/amd64-mingw32msvc-strings
af9cbfed007c6bb158d80c7200a5e85c KNOPPIX/usr/bin/amd64-mingw32msvc-strip
af9cbfed007c6bb158d80c7200a5e85c KNOPPIX/usr/amd64-mingw32msvc/bin/strip
After copying the content of the /KNOPPIX folder and replacing the corrupted files
by the content of the above KNOPPIX_70_fix.tgz file you may want to use the
following command to recreate a corrected KNOPPIX cloop file:
mkisofs -R -U -D -hide-rr-moved -cache-inodes -no-bak -pad KNOPPIX_folder | nice -5 create_compressed_fs - 65536 > KNOPPIX
Then update the sha1sum check file for your new KNOPPIX cloop and recreate the iso.
Please note that the above command requires really a lot of RAM to run properly
and not have corruption as the whole KNOPPIX data content is piped using RAM.
Is this the corruption problem that happened during the English remastering ?
In all cases, I hope that this will be helpful to someone.
Best Regards,
Gilles

How much RAM minimum do you suggest we need?

'really a lot of RAM' is hard to quantify!

Hi ICPUG,
My guess is that in the worse case scenario (of a very slow computer) the amount RAM required
for the pipe to work properly is the size of the data that you need to compress into the cloop file
which in this case is about 9GB. So I would recommend the use of a swap file larger than 9GB.
