Fedora 12, upgrade or fresh-install?

Filed under
Linux

Constantine, Fedora 12 is going to be out soon. I am really excited and I bet every linuxer will be equally excited and looking forward to try it out. Most of the you will be in a dilemma, whether to do an upgrade or a fresh-install? what's best for my system? In this article I will give you some tips and methods which will help you answer such questions.

Don't you just love your system after an upgrade or a re-install? The whole looks and feel has changed, sometimes things that were not working on your previous installation start working , its amazing. Even though you might not agree with me but I believe that the decision that you take at this point, if right, makes you love your new system even more.

Here are some points that you should know before starting:




Flip a coin.

First I back up my important data and try the upgrade option. If for any reason things go tits up then I do a fresh-install and restore my backed up data.

Upgrade should be fine

pacman -Syu

Pacman wacka wacka

What is tis pacman stuff?

re: pacman

yeah, ain't that arch? fedora is yummy.

Full install gives all the goodies

I doubt an upgrade would allow you to change your /boot to Ext4, while a new install will allow you to run the /boot on Ext4 and install Grub2 or whatever so it can boot from Ext4 (something missing until this Oct '09 + distribution versions).

grub2

Oh crap another grub2 distro release? pffffffft

Not grub2

No, Fedora does not use grub2. It uses grub.

re: grub2

one reputable online site said openSUSE used grub2 too, but they didn't. I think folks are getting confused with all the big distro releases so close together.

Fresh install FTW

Real unix/Linux users keep /home on a separate partition and never format it, this way a fresh install is faster than an upgrade.

Just keep note of the config files you edited in the past - shoudn't be more than two or three these days, Linux doesn't need much tweaking anymore - and apply the same changes to the new installation, if still necessary.

Real unix/Linux users also use xfs and not ext4, because xfs is just as efficient but has the advantage of being a proven workhorse: It's been on high-end unix workstations for decades, working through entire projects (from CAD engineering to complex simulations) without a reboot.

wow.

wow, exclude people much? I use ext4, apparently I'm not a 'real unix/Linux user' now? last I checked, Linus uses ext4 too...

Re: wow.

It was more like banter actually, I do make the choices I expressed but far from me the intention of excluding anybody, let alone AdamW and Linus =:O

re: ext4

Is it just me or is ext4 slow? I know it must just be me cause wasn't speed one of its touted features? But every time I install on ext4, the system seems very slow. I tend to do better with ext3. Weird huh?

ext3 vs ext4

Me too! Whats up with that??

ext4 performance

Phoronix comprehensive filesystems benchmark:
http://www.phoronix.com/scan.php?page=article&item=ext4_benchmarks&num=1

It shows that the perceived speed of each filesystem depends on what you do with your computer, because the top contenders - ext3/4 and xfs - are very close to each other, each excelling at different tasks.

I would add though that xfs has an online defrag utility that's far more full featured than e4defrag, so it remains to see how the comparison would look like after one year of usage and doing the correct maintenance to the fs.

Unix filesystem fragmentation is low but it does exist, and if you move around multimedia files day in and day out like in the typical home desktop usage, its effects can be noticed IMO.

BTRFS will catch up with and surpass xfs in speed AND features, with real online defragmentation too; ext4 is an incremental update that doesn't dramatically change the game.

Behind the GNOME 3.22 Release Video

This is less than usual. The time saving mostly stems from spending less time recording for the release video. At first thought you might think recording would be a breeze but it can be one of the most frustrating aspects of making the videos. Each cycle the GNOME community lands improvement a wide set of GNOME’s applications. So before each release I have to find some way to run a dozen of applications from master. I do this either by: Read more

Letter to the Federal Trade Commission regarding Lenovo blocking Linux and other operating system installations on Yoga PCs.

  • Letter to the Federal Trade Commission regarding Lenovo blocking Linux and other operating system installations on Yoga PCs.
    Lenovo just updated the BIOS for the Yoga 710, another system that doesn't allow Linux installs. Wanna know what they changed? Update to TPM (secret encryption module used for Digital Restrictions Management) and an update to the Intel Management Engine, which is essentially a backdoor rootkit built into all recent Intel processors (but AMD has their version too, so what do you do?). No Linux support. Priorities...
  • Microsoft told to compensate customers for Windows 10 breaking computers
    Microsoft has been urged to pay compensation to customers that have suffered computer malfunctions when upgrading to its new software Windows 10. Since the company released the software last year it has been plagued by complaints, with customers claiming their computers upgraded without their permission and, in some cases, completely stopped working. Which?, the consumer watchdog, has told Microsoft to "honour consumers' rights" and compensate those who have suffered from problems, including lost files, email accounts no longer syncing and failed WiFi connection. It said Microsoft customers had also complained that their webcams suddenly stopped working, as did speakers and printers in the wake of the upgrade.
  • Veteran Windows journo slams Microsoft over Surface Pro issues
    Microsoft's tardiness and lack of communication in relation to battery issues affecting its Surface Pro PC/tablet hybrid has been slammed by well-known journalist Ed Bott who has been writing about the company for 25 years. In a column titled "Shame on Microsoft for leaving Surface Pro customers in the dark", Bott wrote that Microsoft had not shown any appreciation of the users who had helped put its Surface business on a solid footing. He wrote that after the Surface Pro 3 had been in the market for more than a year, users began noticing a steady drop in battery capacity. In March 2016, the company's support lines began fielding calls about the issue, with complaints that batteries that should have held a charge for five or more hours were going dead in 20 or 30 minutes and refusing to charge fully.

Android Leftovers

  • Google could be about to reveal its Android and Chrome OS merger
    If you've been following Google for a while you'll know that speculation around the company merging Android and Chrome OS into one single whole isn't anything new, but the rumours have gained fresh impetus over the weekend. Sources speaking to the usually reliable Android Police say Google is preparing to combine the two OSes into something codenamed Andromeda inside the company - that's also the name of the nearest galaxy to the Milky Way or the daughter of Cepheus and Cassiopeia in Greek mythology, depending on which meaning you want to take.
  • Google’s Oct. 4th Event May Reveal Merged Android/Chrome OS
  • Oct 4th rumors: Google to show off merged Android/Chrome OS preview, $69 Chromecast Ultra and $129 Google Home
    Google is holding an event on October 4th, where the company is expected to officially launches its new Pixel and Pixel XL smartphones. But that’s not all we’re expecting to see on October 4th. According to several reports from Android Police, we could also see the launch of Google Home, a Chromecast Ultra, and a new wireless router called Google WiFi. Google may also show off a preview of an operating system that merges Chrome OS and Android, although it’s unlikely to be available to the public before 2017.
  • Android Users Replace Phones Faster Than iPhone Fans
    Every time a new Apple iPhone gets released, it seems like everyone who has chosen iOS over Alphabet 's Android immediately orders one. In reality, however, not every consumer trades in his or her phone just because a new model comes out. They may want to, but leasing cycles, payment plans and other factors influence whether people swap out their iPhone or Android phone after a new model is released. On the Apple side, consumers are actually holding onto their phones slightly longer, while with Android, the replacement cycle has been steady for the past three years, according to data from Consumer Intelligence Research Partners (CIRP).
  • Sony Xperia X Performance users can register for Android 7.0 Nougat beta program (but not everywhere)
  • Leaked Presentation Slide Reveals Sony’s Android 7.0 Roadmap
    If you own an Android device that isn’t a Nexus, chances are you’re probably wondering when your phone will be updated to the latest version of Android, Android 7.0 Nougat. OEMs don’t usually reveal their update plans so early on, but the good news for Sony users is that we now have an idea of when the update will be released. This is thanks to an alleged leaked presentation slide as reported by Mojandroid.sk (via Xperia Blog) from Sony Slovakia. As you can see in the photo above, it shows the company’s plans for the Android 7.0 Nougat update. Assuming the timing is applicable for all markets they operate in, the Xperia X Performance and Xperia XZ should get their update in October.
