Hello!
The size of the operating system distribution image has matter for the legacy systems. Some old PCs and laptops have not DVD but only CD drive and cannot USB boot.
There is a simple way to reduce the size of "bodhi-5.1.0-legacy.iso" (747 Mb) to fit the CD capacity (700 Mb). The way is to exclude from the rootfs "/casper/filesystem.squashfs" two files:
- boot/vmlinuz-4.9.0-6-686
- boot/initrd.img-4.9.9-6-686
The Bodhi installer is smart enough to use kernel and initrd from "/casper/vmlinuz" and "/casper/initrd.lz" respectively.
I use the command to recreate rootfs:
# mksquashfs squashfs-root /isoimage/casper/filesystem.squashfs \
-b 1024k -comp xz -Xbcj x86 \
-e boot/vmlinuz-4.9.0-6-686 \
-e boot/initrd.img-4.9.0-6-686
This reduces the size of resulting ISO image to 687 Mb.
My suggestion is to create a CD-size image and place it to the distribution site for everyone.
Thank you.
