content of rootfs1-2-3-4 on rolling .iso

Hello,

I have been working on a remaster of Slitaz as a school project, so far so good thanks to tazlito awesome scripts.

My remaster is aimed to let other students with old computer to use Linux, and I included several applications.

Also, it is meant to be mostly installed rather than run in RAM, and likely not on UEFI computers.

I have a couple of questions regarding the 4 rootfs.gz files in the boot and efi folders of the sliaz-rolling.iso.

1) what is their contents? (meaning, are they different and separate flavors or do they add on to each other depending on the booting option selected?

2) if I make an iso not to be used on efi computers, can I delete the efi folder of eliminate some of the rootfs files?

Thanks.

1) See http://doc.slitaz.org/en:guides:manyinone?s[]=russian&s[]=dolls

2) You can remove efi/boot and boot/isolinux/efi.img but the files, bzImage and rootfs*.gz are

   hard linked in efi/boot boot/iso and into boot/isolinux/efi.img. You will spare only 3*2kB for

   efi/ and 116kB for boot/isolinux/efi.img (the boot sector, 2 fats and the directories)

# du -chs efi boot

52M    efi

108M    boot

160M    total

# df -h .

Hi Bellard,

thanks for the prompt answer.

The link was very interesting, I might even be tempted to experiment with the idea of a small flavor to boot and install a larger flavor on a low RAM computer.
