Problem genisoimage

[renpa]

My problem is that when I go to remaster a Knoppix 6.7.1 CD uncompressed in
directories (not partitions) I find that the package mkisofs is
integrated into genisoimage and to create compressed KNOPPIX image and pass the following
I get the following error:
mkisofs -input-charset ISO-8859-15 -no-split-symlink-components -no-split-symlink-fields
-R -l -U -V "KNOPPIX filesystem" -P "KNOPPIX www.knoppix.net" -hide-rr-moved
-cache-inodes -pad /home/knx/knxmaster/master | create_compressed_fs - 65500 >
/home/knx/KNOPPIX/KNOPPIX
bash: mkisofs: no se encontró la orden
2 processor core(s) detected
Warning, number as file string found. Assuming old command syntax and
choosing compatible parameters (-m -B 65500). See the usage info (-h)
for better/correct parameters.
Block size 65500, expected number of blocks: 2147483647
I tried with genisoimage proving the following:
genisoimage -R -U -V "KNOPPIX.net filesystem" -publisher "KNOPPIX www.knoppix.net"
-no-bak -quiet /home/knx/knxmaster/master | /usr/bin/create_compressed_fs -B 65536 -f
/opt - /home/knx/KNOPPIX/KNOPPIX

2 processor core(s) detected
ERROR: Opening temporary file. Exiting...
Warning: creating filesystem that does not conform to ISO-9660.

where is the error? thanks.

Follow http://knoppix.net/wiki/Knoppix_Remastering_Howto
and work as root!

Werner, I work as user ROOT! Thanks, but I still have the problem..

[Werner P. Schulz]

... and what's about the HowTo? I've rewritten it and tested carefully.

[renpa]

Werner, thank you.
failure is to specify the file to opt

genisoimage -R -U -V "KNOPPIX.net filesystem" -publisher "KNOPPIX www.knoppix.net"
-no-bak -quiet /home/knx/knxmaster/master | /usr/bin/create_compressed_fs -B 65536 -f
/opt/rem.iso (for example) - /home/knx/KNOPPIX/KNOPPIX

... and what's about the HowTo? I've rewritten it and tested carefully.

If you use the '-f ' option of create_compressed_fs you have to specify the complete filename for the temporary file. /opt is usually a directory. If you create a temporary file in this directory it is created inside the persistent image if you have flash install of Knoppix. This would result in slow system performance. If you have a sufficient huge ramdisk you could create the temporary file there. I would recommend that you use an HDD for this temporary file.

Wow!!! Klaus, thank you very much. The file especify in /opt as .iso temporary file to create la image...
With genisoimage result:
