[Fedora-livecd-list] RFC- proposal for livecd filesystem layout changes

[Douglas McClendon]

This is a (set of) proposal(s) that I don't feel too strongly about, but 
if people agree, I wouldn't mind implementing.

First, I'd like to put together and submit a patch, that moves the 
placement of  /squashfs.img in the livecd iso to /LiveOS/squashfs.img

This would have the benefit of cleaning up some code that differentiates 
between that placement on live-usb, and the current /squashfs.img on 
current live-isos.

Another benefit is making the iso directory structure look nicer and 
more intuitively understandable for someone looking at it under windows.

A downside, is that an F7 version of livecd-iso-to-disk would not work 
with an F8 livecd.  I think its worth it, but I admit it is a downside.

Also, livecd-iso-to-disk would look a bit uglier, if it needed to 
maintain the ability to support livecds made with the current scheme.

Along the same lines, I also suggest moving /isolinux(livecd) and 
/syslinux(liveusb) to /boot/isolinux and /boot/syslinux.  This also 
would make the usb/iso directory structure look cleaner and more 
intuitively understandable to less linux-guru users when they look at 
the directory structure under windows (or anywhere)

And because it is somewhat on-topic, I would also suggest changing the 
current squashfs.img:/os.img to be squashfs.img:/ext3fs.img, as that 
would be consistent with what it is named in the --skip-compression case.

Also, I would modify the above to be ext3.img instead of ext3fs.img, 
such that the naming convention is consistent with squashfs.img (i.e. 
name of filesystem as passed to mount -t).

Finally, I would suggest changing squashfs.img:/ext3.img to 
squashfs.img:/LiveOS/ext3.img, such that the general idea is that a 
container filesystem such as squashfs presents the result in the same 
place you would look for it without the extra container filesystem.
