I'm laughing with you. Bleeding edge 'users'.

cant keep my fingers off the keys and out of the system ,,,,,,,,,,LOL

When I decide to try something 'major', I make a clone of my partitions first. So much easier to restore what you 'had'!

that is a good point ,,,,,,,,I have never done that .

what do you use ,,, "dd" ?

Clonezilla. It hasn't failed me yet.

[vinnywright]

well I I just tested the low latency kernel ,,,,,,,with a avconv x11grab with sound (internal sound card) on a amazon prime video playing full screen ,,,,,,,,,,,,, last time on a stock kernel their was a noticeable lag in audio ,,,, this time ,,,,,perfect.

Muahaha

now we will se if their is any difference in quality of DeVeDe project or not ,,,,,,,not that thay have ever been bad ,,,,,just a wandering .

Use btrfs and snapshots. Just roll back...

[SteveRiley]

Btrfs snapshots would be the ideal mechanism here. Take a snapshot, make your changes, watch them fail, revert to your snapshot. I bet Oshun could go on and on and on and on here

yes it would ,,,,,BUT I have not installed anything to the btrfs drive as yet ,,,,,,,,,,,,unless your saying I could take a btrfs snapshot of a ext4 partition

I doubt that's possible

If you had used Btrfs rather than EXT4, then it would have been very easy to prepare for an experiment -- snapshots are cleaner than cloning a drive, especially if the experiment failed. With snapshots, you can roll back to the system state before the experiment. With clones, you'd have to restore the clone to your primary drive.

[GreyGeek]

You can convert you EXT4 partition to btrfs.

[SteveRiley]

You can convert you EXT4 partition to btrfs.

Yep, that's definitely the case...Vinny has even reported that here before.

But a Btrfs snapshot of an EXT4 partition? Not likely

Did you say "experiment" ,,,,,, my inner geek is getting exited .

Plan > do install to the btrfs drive > take snapshot > from in install on btrfs drive do "sudo rm -rf /bin" (DO NOT DO THIS YOU WILL BE HOSED) then roll back the snapshot and see if we are good.

I did accidentally do that one time (no sudo ,,,it was Slackware and I was root) at first I thought it didn't do anything (maby I didn't really hit the enter key ) the screen was still their ,,,,the cursor moved ,,,,,,but nothing would take a click or run .
luckily I had a duplicate install and just copied /bin back and all was good .

Eager to read the results of your experiment!

prob. wont happen till sat. night ......but it will happen

Eager to read the results of your experiment!

step 1 complete .............. installed Netrunner-15-Prometheus to the btrfs drive and it's grub to the partition IE: btrfs drive is /dev/sdb1 and grub installed to /dev/sdb1 however none of the other installs grubs OS-probers would find it .

So did an edit of /etc/grub.d/40_custom on the 14.04 install and added

menuentry "Netrunner" {
insmod gzio
insmod part_gpt
insmod part_gpt
insmod btrfs
set root='(hd1,gpt1)'
configfile /@/boot/grub/grub.cfg
}

a "sudo update-grub" reboot now I am in .................................................. ..........

ya tree view @hear

but the install allso left these 2 hear in red

vinny@vinny-Bonobo-Extreme:/mnt/btrfs$ ls
@  @data  @home  kubuntu  [COLOR=#ff0000]ubiquity-apt-clone  var[/COLOR]

the ubiquity-apt-clone contanes

vinny@vinny-Bonobo-Extreme:/mnt/btrfs/ubiquity-apt-clone$ ls
apt-clone-state-netrunner.tar.gz

and the /var contans /lib that is empty ??

well hear is what we are going to kill ,,,,,,and then try to revive with a snapshot ,,,,,,,,,, getting late @hear so the beheading will be postponed till tomorrow or so ........ I await suggestions on how to proceed .
