Hi

I did try to mount the CD rom in loop on the iso-file as following:

Code:
mount -o loop /mnt/sda6/stocks/isos/qrky-120.iso /dev/sr0


after that, it is possible to read the ISO as if it would be the CDROM but not to start properly the remasterisation (Quirky 120 from qrky-120.sfs because I will try to eliminate seamonkey, geany, abiword and gnumeric, to make the new ISO lighter, and replace by the content of the KDE4 according to the discussion http://www.murga-linux.com/puppy/viewtopic.php?t=57450 and sfs)

a file usage of Xdialog appears.

nothing happens.

an other way?

bye

hmmm, /dev/sr0 isn't a directory.
Are you sure about the command?

Hi oui,

You can do a manual remaster. I just remastered Lupu 5.11 this way and these are the notes I kept. I did the work on my sdb7 partition so change that part to your partition.

hand mount sdb7, (a separate ext2 partition on my hard drive)

mkdir /mnt/xx
mount /dir-where-iso-is/lupu-511.iso /mnt/xx -o loop
chdir /mnt/xx
mkdir /mnt/tmp

mount lupu-511.sfs /mnt/tmp -o loop
mkdir /mnt/sdb7/build

Use Rox to copy all files from /mnt/tmp to /mnt/sdb7/build

umount /mnt/tmp

Now you can edit the files in /mnt/sdb7/build, as desired.
Then put it all back together.

chdir /mnt/sdb7

mksquashfs /mnt/sdb7/build new-lupu.sfs

Use Rox to delete all files from /mnt/sdb7/build

Copy the new-lupu.sfs to /mnt/sdb7/build

Rename /mnt/sdb7/build/new-lupu.sfs to /mnt/sdb7/build/lupu-511.sfs

Copy all other files (except lupu-511.sfs) from /mnt/xx to /mnt/sdb7/build

umount /mnt/xx

chdir /mnt/sdb7

mkisofs -o XXX.iso -b isolinux.bin -c boot.cat -no-emul-boot -boot-load-size 4 -no-iso-translate -boot-info-table build/

Done.
The new XXX.iso is in /mnt/sdb7

HTH

This is a bug in remasterpup versions 2 & 3.
There's a botched regex in the handling of the VIRTUALCD variable.
To fix it, replace where it says:

Code:
sed -e 's/on[ ].*+//'


with this:

Code:
sed -e 's/on [ ]*//'


(mind the blanks).
