Last night, I downloaded the installation DVD for Fedora 12 x86_64.
Checked the sha256sum of the iso file, then mounted it on my web server
and extracted the file install.img from the images directory. Then
plugged in my USB stick and used dd as root to write install.img to the
stick like so:
[root@deafeng3 Fedora-12-Alpha-x86_64-DVD]# dd if=install.img of=/dev/sdb
239392+0 records in
239392+0 records out
122568704 bytes (123 MB) copied, 2.40894 s, 50.9 MB/s
[root@deafeng3 Fedora-12-Alpha-x86_64-DVD]# umount /dev/sdb1
Then I unplugged the USB stick and plugged it in again to the same USB
port, just so I could check on whether I did the dd correctly. I got the
following in /var/log/messages:

Summary:
SELinux is preventing mount (mount_t) "mount" unlabeled_t.
Detailed Description:
SELinux denied access requested by mount. It is not expected that this
access is
required by mount and this access may signal an intrusion attempt. It is
also
possible that the specific version or configuration of the application is
causing it to require additional access.
Allowing Access:
You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Or you can
disable
SELinux protection altogether. Disabling SELinux protection is not
recommended.
Please file a bug report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi)
against this package.

Any ideas about whether this will be a problem for purposes of
installing Fedora 12 on a brand new hard drive?
