Hi,
the problem I see is that the
/tmp filesystem is too small to store the temporary files needed to build the ISO:
i.e. you are going to remaster approx. 3.8 GB, that once compressed will result in something like 1.3 GB, that the required free space in /tmp.
It appear you have enough free space on '/' filesystem, i.e. 33 GB free, so I suggest this:
umount -a
mkdir /temp # this will create a temp dir on / filesystem
mylivecd --gzip --tmp /temp --nodir ^/temp mylivecd.iso
the
--gzip option provide lesser compression but it is approx 3x faster, good for testing,
the option
--tmp /temp tell to mylivecd program to store the temporary files in
/tempthe option
--nodir ^/temp tell to mylivecd to not backup /temp directory (should be excluded automatically ... just to be sure).
