Found this bug while testing Dracut: https://fedoraproject.org/wiki/Test_Day:2009-08-27_Dracut . If you take the live image from that page, convert it to a live USB image with livecd-iso-to-disk, and try and boot it, it fails. To make it work you have to edit the kernel command line and change: root=live:LABEL=blahblahblahblah to: root=live:LABEL=LIVE i.e., the label that's written to the filesystem by livecd-iso-to-disk does not match the label it puts in the bootloader configuration. Some additional comments from IRC: <haraldh> it generates the wrong kernel command line <haraldh> or labels the filesystem wrong <haraldh> either way <adamw> why does it work with the old initrd system then? :) <haraldh> ah, for dracut they generate a rule <haraldh> if the LABEL is recognized <haraldh> then the partition is mounted <haraldh> and the squash image is mounted <haraldh> so if the partition label does not match the label on the kernel command line <haraldh> well <haraldh> it's dracut specific <haraldh> so definitely a new codepath This is high severity and a release blocker because converting the live CD images to USB images is a very common thing for people to do, and if we were to release F12 with this broken, it'd be a significant problem.
This hit the recent "F12 snapshot 1", reported as Bug 521471
I am also running into this. root=live:LABEL=LIVE does not seem to work for me as a workaround, though (on my own livecd-creator-created ISO). Is there a way to get the correct LABEL somehow?
Use /sbin/dosfslabel or /sbin/e2label (depends on partition type).
Thanks Bob - yes once you have the correct label and apply it to the kernel boot line then it does boot correctly.

It appears the only way I could recover from this above error was to reformat the disk. fsck couldn't fix it.
I suspect that dracut insisting upon a LABEL might be wrong. mkfs.vfat creates filesystems with a blank label. We should require setting a label in order to use this? mkliveinitrd did not have this requirement right?
Still happens in snapshot 2, but I guess that was expected.
This bug was reviewed at the Fedora 12 Beta Blocker bug meeting on 2009-09-18. It is believed to be fixed in livecd-tools-028-1.fc12. It needs to be retested. Please help us by reporting if the latest package addresses the originally reported issue. Thanks.
I'll try testing tonight; But the fix should really get pushed to F11 (& F10?) since the F12 live media will probably be generated on a user's F11 system.
The bug was written to the .ISO file itself. The old livecd-iso-to-disk should (theoretically) handle it just fine. http://alt.fedoraproject.org/pub/alt/nightly-composes/ I did not test writing the ISO to LiveUSB using liveusb-creator. Could someone test that with a nightly Live images?
to be clear - this should be fixed in any nightly build dated 20090918 or later. -- Fedora Bugzappers volunteer triage team https://fedoraproject.org/wiki/BugZappers
Just tested using both: http://alt.fedoraproject.org/pub/alt/nightly-composes/xfce/xfce-i386-20090917.16.iso http://alt.fedoraproject.org/pub/alt/nightly-composes/desktop/desktop-x86_64-20090917.16.iso I've verified that the problem's fixed in these generated images. The syslinux.cfg entry now loads the root by UUID instead of LABEL; Example: append initrd=initrd0.img root=live:UUID=6C3A-9A46 rootfstype=vfat rw liveimg overlay=UUID=6C3A-9A46 quiet rhgb Both images boot and bring up a login. The desktop-live image is healthy. The xfce-live image has gdm(?) issues, but startxfce4 runs fine by hand from a text console. Looks like *this* bug is fixed.
Professional dissertation writing services are not cheap. You can expect to pay anything from $1,000 to $5,000 for a dissertation or thesis. The most expensive services will charge you up to $10,000 or more. The price of the service https://ask4essay.com/how-much-does-professional-dissertation-writing-services-cost/ is determined by the level of expertise and experience that you require. If you want an experienced writer who has written dissertations before and has an excellent track record then it will cost more than someone who is new to the profession and does not have as much experience.
