Good luck partitioning a disk in any sort of way with Yum. Well, I take it that you are aware that cd media is not normally partitioned (it is for bizarre things like Apple Mac OS X install CD's using Apple Partition Map; but that is totally not relevant for a Fedora Live CD on any architecture we want to support). So I assume you are talking about creating Live USB images, e.g. an image people can dd(1) to the USB key e.g. # dd if=some-image.img of=/dev/sdb where /dev/sdb is the block device for your USB stick. First, pilgrim supports this (partitioning is not hard), it was the first installation target since that is what we use for OLPC; see http://wiki.laptop.org/go/OS_images_for_USB_disks for details. Second, a Fedora system on a USB stick / hard disk is useful.. Heck, this can be done today with the pilgrim system by simple changes to streams.d/fedora-base.stream in the pilgrim source tree (just define a new variant, liveusb, where PILGRIM_FS_liveusb=ext3). The reason I haven't done this is just lack of time. And motivation. The lack of motivation has to do with the fact that I'm not sure how useful it is since ext3 basically is pretty wasteful and have no compression [1]. To have any kind of useful system you'd need a 2GB or bigger stick. Second, I think once we get the "install to hard disk" feature done people can just install the OS to a USB stick / hard disk from the livecd and be done with it. That will also ensure that we fix up the UUID of the file system and other stuff. We can easily add variants for "usb stick" builds until we have the "install to hard disk" feature. But I'd rather that we worked on the latter, that feature is so much more important for Fedora as gdk so eloquently points out. We could also add a new hack to use squashfs / ext3 / dm-snapshot hacks to the live USB image where the overlay lives in a file on a different partition of the USB stick. That way we'd have a semi-useful system that would fit on a 512MB stick. Again, not sure how useful live USB is, I'd rather focus on getting the "install to hard disk" feature done and just tell people to install to a USB stick / harddisk if they want a portable Fedora OS. David [1] : though I did read something about "compressed block devices" being added to Linux. Dunno where that is going. -- Fedora-desktop-list mailing list Fedora-desktop-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-desktop-list
