filesystem.squashfs larger than 4GiB

[Narcis Garcia]

Building fails if the resulting ISO is larger that 4GiB, when I tried to make a Live-CD / Live-USB with a lot of software:

Preparing directory for new files
Updating md5sums...
~/tmp/remaster-iso ~
~
Packing ISO image...
ISO description set to: Mubuntu1210
File /home/user/tmp/remaster-iso/casper/filesystem.squashfs is larger than 4GiB-1.
-allow-limited-size was not specified. There is no way do represent this file size. Aborting.
Failed to pack ISO image, error=1

UCK 2.4.5 is severely outdated, please do use the 2.4.7 from the PPA:

Also it may not be possible to have files > 4GB on an ISO9660 filesystem (as noted there are possible workarounds, but they seem to have only limited compatibility):
http://en.wikipedia.org/wiki/ISO_9660#The_2.2F4_GiB_file_size_limit

So it's probably best to reduce the content, so it'll fit in 4GB.

The target of the big file is a Live-DVD or Live-USB to boot GNU/Linux system, which has no problem with files larger than 4GiB.
How can I make UCK to use -allow-limited-size parameter and generate a big Squash file?

I don't care about MS/Windows or Mac limitations, because I want to boot a GNU Live system, and in some cases from a USB stick.

[Pascal de Bruijn (pmjdebruijn)]

Considering UCK is written in Bash, it should be trivial to add, grepping the sources reveals the following script to generate to ISO using genisoimage:

/usr/lib/uck/remaster-live-cd.sh

I 've got the same problem than Narcis Garcia.
I would like to know if you find a solution to uncountered this problem.

Thanks

is a bad idea to add in script: /usr/lib/uck/remaster-live-cd.sh

-allow-limited-size -udf
