Bug 490843

I have detected the same issue here with liveusb-creator-3.6.5-2.fc10.noarch. I will attach two files including the output of liveusb-creator (liveusb-creator-output.txt) and the liveusb-creator.log.

Well, the sys.popen() (as the current implementation uses) doesn't seem to be 
very sane. According to http://www.python.org/dev/peps/pep-0324/, there are 
many better ways to do such things. And just doing '%s' will not solve your 
problems, as really any character can show up in the label name of a volume - 
including space, comma and quotations (all of them I've already seen in the
real life unluckily).

If a label of a medium would be " ; rm -rf /; " (without the ""), that even 
would cause damage. Thus this is IMHO considered to be a security issue...

I discovered that installing Fedora 12 Beta (F12-Beta-i686-Live.iso) with liveusb-creator-3.7.1 under Windows XP on a usb flash drive that contains spaces in its volume name creates an image, that fails to boot. After attempting to boot from the usb drive, the following message appears:


No root device found


No root device found

Boot has failed, sleeping forever.


Fedora 11 (Fedora-11-i686-Live.iso) boots fine, but it seems that it fails to find its persistent overlay, so the changes to the file system are lost after reboot, even if you did create a persistent overlay.

The created syslinux.cfg (for Fedora 12 Beta) file contains the following kernel parameters:

label linux0
  menu label Boot
  kernel vmlinuz0
  append initrd=initrd0.img root=live:LABEL=USB_DISK rootfstype=vfat rw liveimg overlay=LABEL=USB_DISK quiet  rhgb

The volume name of the usb disk is "USB DISK".

The liveusb-creator does not use sys.popen, and never has.

robert@tux:~/liveusb-creator-3.7.3 > grep -r extlinux *
liveusb/creator.py:              os.path.join(syslinux_path, "extlinux.conf"))
liveusb/creator.py:    self.popen('extlinux -i %s' % syslinux_path)

Whatever *.popen is used - it's still a broken implementation and spaces still
seem to cause trouble.

This message is a reminder that Fedora 10 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 10.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '10'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 10's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 10 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

Bumping to 12 as it's been reported to occur there.
