Goodbye Debian, Hello Sabayon

post #1 of 9
Thread Starter 
Ok, so as someone who first learned linux with gentoo ::cowers in fear::, i've always been partial to having more control over your OS, debian allows it, but gentoo just makes it more mandatory..

With that in mind, i was playing with sabayon for a while about a year ago when 3.25 was out, it was beautiful, but a bit slow, and the liveCD was bad to the point of it being unheard of. As i got screwed by debian for the last time last night, i torrented Sabayon 3.4 (64 bit), got 1..4 MB/s, had it downloaded in about an hour. Burned it to a disk, and as soon as i started the computer, saw an instant difference, the Live CD ran, booted up at the normal time for a live cd, and somehow managed to run very quick once going (granted, i have 4 Gb of RAM)

I backed up my files and am losing Debian/Ubuntu and XFS in one stroke. I hear that ext3 can be brought close to xfs speedds by properly using tune2fs.

So on that note, I'll report back on this beauty, and has anyone done much with tune2fs and supercharging ext3?

Sabayon is fantastic; I loved it, although I spent little time in it.

One bug I know of is that if you use autologin, log out at any time, then log back in, you won't be able to access your KMenu. If you try to do so, you will lose all access to your Panel, and the only way to get back to normal is to right-click the desktop, hit "logout," and then restart the computer.

Also, I didn't know how to use the "Portato" package manager, but that's because I didn't spend much time in Sabayon. But it is, by far, the best looking distro out of the box with the right packages pre-installed.

Yeah, I've got it up and going now, looks beautiful as usual, and still wrangling my way into working dual monitors and getting nVidia Cuda up and running again.

On top of that, i think we're in business! And its made in italy, whats not to love!

A very simple tweak is to add "noatime" to the options for your root file system in /etc/fstab. (This will disable file access times and thus increase general HD responsiveness). For example, here is my root line:
Code:
/dev/sda1 / ext3 defaults,noatime,data=writeback 1 1
Now, the other thing I recommend doing is adding the "data=writeback"; but it has a shortcoming. Your data will not be as recoverable if the drive crashes - and some of the recovered data might be old versions. Not an issue I've ran into though.

A few steps involved. First add the option to your fstab. Then open Grub's menu.list wherever it is kept on your system and add "rootflags=data=writeback" to the "defoptions" and "altoptions" lines. Then update Grub (su root; update-grub).

Finally we get to tune2fs. After all the above is complete, run this (subbing in your hard drive paths for mine, obviously):
Code:
tune2fs -o journal_data_writeback /dev/sda1

Personally I prefer ReiserFS, but I can get off OK with ext3 too.

Hows the package management? How many apps can you add as compared to xBuntu?

I've never used Portato, it's GUI package manager, but I know it works with the Emerge library from Gentoo. Emerge offers most everything APT does, and probably a few more bleeding edge things.

Well thats cool... My last experience with Sabayon was less than likable... But I'm always willing to try new stuff.. I see the new release has plenty of coolness,,, The last time I tried it the package management was horrible!!! I'll give her w whirl!!!

Writeback changes the ext3 journaling mode to less securely write file information changes and store that data in fewer places (thus the increased difficulty in recovering last data, and why a old version of the file might be recovered). I know thats a pretty crappy explanation, so I did some digging in the RedHat whitepapers on ext3.

Quote:
journal - logs all filesystem data and metadata changes. The slowest of the three ext3 journaling modes, this journaling mode minimizes the chance of losing the changes you have made to any file in an ext3 filesystem.

ordered - only logs changes to filesystem metadata, but flushes file data updates to disk before making changes to associated filesystem metadata. This is the default ext3 journaling mode.

writeback - only logs changes to filesystem metadata but relies on the standard filesystem write process to write file data changes to disk. This is the fastest ext3 journaling mode.
