Creating a Linux Live USB stick: Big win for Fedora

Three times now I've gotten myself into a situation where I was trying to install Ubuntu and for some reason couldn't burn a CD. So I thought hey, maybe I can make a bootable USB image on this handy thumb drive here. And spent the next three hours unsuccessfully trying to create one. And finally gave up, got in the car and went to buy a new CD burner or find someone who could burn the ISO to a CD because that's really the only way you can install or run Ubuntu.

There are tons of howtos on the web for creating live USB sticks for Ubuntu. Almost all of them start with "First, download the CD image and burn it to a CD. Now, boot off the CD and ..."

The few that don't discuss apps like usb-creator-gtk or unetbootin tha work great if you're burning the current Ubuntu Live CD image from a reasonably current Ubuntu machine, but which fail miserably in every other case (wildly pathological cases like burning the current Ubuntu alternate installer CD from the last long-term-support version of Ubuntu. I mean, really, should that be so unusual?)

Tonight, I wanted a bootable USB of Fedora 12. I tried the Ubuntu tools already mentioned, but usb-creator-gtk won't even try with an image that isn't Ubuntu, and unetbootin wrote something but the resulting stick didn't boot.

I asked on the Fedora IRC channel, where a helpful person pointed me to this paragraph on copying an ISO image with dd.

Holy mackerel! One command:

dd if=Fedora-12-i686-Live.iso of=/dev/sdf bs=8M
and in less than ten minutes it was ready. And it booted just fine!

Really, Ubuntu, you should take a look at Fedora now and then. For machines that are new enough, USB boot is much faster and easier than CD burning -- so give people an easy way to get a bootable USB version of your operating system. Or they might give up and try a distro that does make it easy.

Fedora 11 not encouraging so far

Noticing that every article I write ends up including a section on "This doesn't work under Ubuntu; here's a link to the year-old bug with a patch and several workarounds," I decided to try Fedora 11 and see if it was any better.

I downloaded and burned the latest netinst CD ISO and booted it on the Atom machine. It greeted me with this prompt:


    1.
    2.
Select CD-ROM boot type: 

I am not getting warm fuzzies about Fedora being the solution to the Linux distro problem.

What do you think? Should I choose 1. or 2. ?

Fedora Core 3

Fedora Core 3 is finally out, so I tried it this evening.

The install itself went apparently smoothly, looking just like a normal Redhat graphical install, with a few new options, such as SElinux (which I turned off).

The first problem came during the first boot of the newly installed system, when the boot process complained that fsck.ext3 was finding errors on hda2.

hda2, on this disk, is a SuSE partition: I didn't tell the FC3 installer about it at all, so, correctly, it's not mentioned in /etc/fstab; and it's reiser, so FC3 has no business running fsck.ext3 on it!

It dumped me into a single-user shell, in which mount shows / as mounted "rw,defaults", but any attempt to modify anything on the root partition complains "Read-only file system". I got around that with mount -o rw,remount / -- it turns out that typing "mount" doesn't actually give an accurate picture of mounted filesystems, and cat /proc/mounts is better.

Now able to edit /etc/fstab, I noticed the "LABEL=/" and "LABEL=/boot" entries that Redhat is so fond of, and speculated that this is what was causing the problems. After all, there are several other OSes installed on this system (a Redhat 7.3 and a SuSE 9.1) and either or both of them might already have claimed the label "/". So I changed the fstab entries to /dev/hda6 and /dev/hda1. A reboot, and voila! things worked and I found myself in the first-time boot configuration process.

(Note: Redhat bug 76467 seems to cover this; I've added a comment describing what I saw.)

I really wish Redhat would get over this passion for using disk partition labels, or at least detect when the labels it wants to use are already taken.

Onward through hardware configuration. It didn't detect my LCD monitor, but that was easy to correct. It correctly detected and configured the sound card. It didn't try to configure a printer. At the end of hardware configuration, it took me to a graphical login screen (no option for non-graphical login was offered), and I logged in to a gnome desktop, with a rather pretty background and some nicely small and professional looking taskbars. The default gnome theme looks nice, and the font in the terminal app (gnome-terminal) is very readable on this 1280x1024 monitor. The default browser is Firefox, one of the 1.0 preview releases, with nice looking fonts.

The first step was to try and configure a printer. Double-clicking on the "Computer" desktop icon offered only my two optical drives, the hard drive, and "Network". The Redhat menu in the panel, though, offered "System Settings->Printer", which ran printconf-gui, which revealed that FC3 had in fact autodetected my Epson Photo 700 and configured it. Strangely, printconf-gui's "Test" menu was greyed out, so I wasn't able to "print a test page" that way. I tried quitting printconf-gui, restarting it (still grey), left-clicking on the printer (still grey), right-clicking on the printer (nothing test-y in the context menu) -- and the Test menu finally ungreyed! The test page printed beautifully -- centered on the page, something Debian's CUPS setup has never managed.

Clicking on the red ! in the taskbar took me to up2date; clicking through the screens ended up updating only the kernel, apparently because updates aren't auto-selected and I have to manually "Select all" in order to update anything. Once I figured this out, up2date, via yum, got started updating the other 75 available packages. But it only got halfway through before it hung (the window wouldn't repaint). It turned out that kill -1 on the up2date process didn't help, but kill -1 on the /usr/bin/python -u /usr/sbin/up2date made the window wake up and start updating again. I had to repeat this several times during the multi-hour update. Then it died, apparently with no memory of which systems it had already updated.

A Fedora expert suggested that I should

Indeed, that seems to be working much better, and it turns out that I can move the RPMs already downloaded from /var/spool/up2date to /var/cache/yum/updates-released/packages so I don't have to re-download them (whew!)

Mixed review

So overall, FC3 gets a mixed review. The installer is pretty good. It's a bit light on feedback: for instance, not telling me that a printer was configured (or giving me an option to change it), which would have added a warm fuzzy since it turned out it handled it so well; or not giving me a non-graphical login option. The desktop look is clean and usable.

OTOH, the boot totally failed due to the LABEL=/ problem, and up2date totally failed. A novice user, wiping out the disk, wouldn't see the partitioning problem, but if up2date is as flaky as it seems (everyone I talked to has had problems with it) it's hard to understand why they don't just use yum directly, and offer more mirror options (up2date only gave me a choice of one server, which was obviously overloaded).
