Hi.
My story:
I used to edit the rootfs.gz file when I used Slitaz-4.0-core.iso.
I did that with those commands:
---start
(zcat rootfs.gz 2>/dev/null || lzma d rootfs.gz -so) | cpio -id
rm rootfs.gz
#edit some files
find . -print | cpio -o -H newc | lzma e -si -so > ../rootfs.gz
---end
Now, I use slitaz-rolling-core.iso downloaded from here: http://mirror.slitaz.org/iso/rolling/
Those commands do not work any more. I get this error: http://forum.slitaz.org/topic/slitaz-50-rc1-crashing-on-boot-up-with-kernel-panic-please-help
...even if I use the rolling version, and even if I do not edit anything.
The strange think is that the rootfs.gz file genrated by the command:
tazusb writefs lzma
works great!
So, I think you might have changed something to those 2 commands:
#extract command
(zcat rootfs.gz 2>/dev/null || lzma d rootfs.gz -so) | cpio -id
#compress command
find . -print | cpio -o -H newc | lzma e -si -so > ../rootfs.gz
which I've found here: http://doc.slitaz.org/en:handbook:hacklivecd .
Thanks for help!
