unmount failure kaboom
by Warren Togami 19 Feb '08

19 Feb '08

chroot-creator does: creator.mount() # --bind mount a directory like /opt/ltsp/i386 upon instroot creator.install() creator.configure() creator.unmount() # Umount all the bind mounts then unmount instroot ... creator.cleanup() # Recursively delete the temp directory Between unmount() and cleanup() in other LiveCD workflows is a time consuming step where an image is created. Unfortunately, in my case there is no time consuming step between unmount() and cleanup() which sometimes leads to this failure: Installing: xorg-x11-drv-spaceorb ##################### [308/308] umount: /var/tmp/imgcreate-C_SsuB/install_root: device is busy Thankfully none of the bind mounts from the host were still mounted during the recursive delete. But it did blow away the payload of the chroot-creator run. Is there any safe way to detect that processes within the chroot are truly done before trusting that the unmount was complete?

ChrootCreator class and chroot-creator tool - install to a target chroot directory It does not change the behavior of any existing user of LiveCD tools. This is a slightly updated from my previous post 3 days ago. Warren Togami wtogami(a)redhat.com

Live ISO within initrd for PXE Boot?
by Warren Togami 18 Feb '08

18 Feb '08

http://git.fedoraproject.org/git/?p=livecd;a=commit;h=e0f0269d3a8f8f310e7c5… > > The way it works is to bundle the complete ISO image inside the initrd. > The kernel and (bloated) initrd are downloaded using PXE in the normal > way, and the init script finds and loopback-mounts the ISO image and > booting continues as normal. Wow. I don't mean to offend, but this seems like an incredibly bad way of doing this. Isn't this really slow in the boot up because you must wait for the entire ISO to download? It also requires the client to have more than enough RAM to have the entire ISO in memory? It sounds like the entire memory used by the ISO remains unavailable to the booted system. I need something similar to boot read-only OS images over PXE boot for LTSP. Upstream LTSP5 uses nbd to serve a raw squashfs image as a network block device, which means only a tiny bit needs to be in the initrd and very little memory overhead. Parts of the read-only image are streamed over the network on demand. I'm waiting on Jeremy to get back regarding a long-term plan for supporting mayflower-like things within mkinitrd itself. NBD support was not accepted into mkinitrd because it would rely upon mayflower-like functionality to do right. Warren Togami wtogami(a)redhat.com

Creating i386 LiveCD on x86_64 Fedora
by Gain Paolo Mureddu 16 Feb '08

16 Feb '08

Hello, I'm terribly sorry if this has already been asked, and thus answered. I'm trying to generate an i686 LiveCD image on an x86_64 Fedora, how can I force the packages to be fetched and "installed" be those for i686, or do I need to be running an i686 Fedora? Thanks in advance.

livecd-iso-to-disk
by Gary Thomas 15 Feb '08

15 Feb '08

The documentation on 'livecd-iso-to-disk' is pretty thin. My main [first?] question is once I create such a USB-stick image, how do I boot it? Do I have to have a machine with a BIOS that understands such? Thanks for any help/pointers -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------

class ChrootCreator for Review
by Warren Togami 15 Feb '08

15 Feb '08

Hi folks, I am attaching changes that implements class ChrootCreator, allowing you to install into a target chroot. chroot-creator is the frontend script that uses this new class. ChrootCreator is similar to existing uses of ImageCreator except the installed chroot is not destroyed after it is done. Any comments to improve this? Warren Togami wtogami(a)redhat.com
