Updating tzdata

The Android core libraries team will provide the necessary data files for updating time zone rules on a stock Android device.

OEMs can choose to use these data files when creating time zone updates for their devices or can create their own data files if preferred.

You can acquire account for this subscription process on Red Hat portal as a Red Hat developer.

Now login to your system and check your subcriptions status.

So if something went wrong in the rpm update or you want to revert to the prior copy of the OS/filesystem, you can boot back into the snapshot, using subvolid=256 as filesystem mount options for / in fstab.

If you want to just default to the snapshot then you can run btrfs subvol set-default 256 and you are just running from the old snapshot state going forward.

ok so now it's Monday and I found a few minutes to continue my weekend project at work :)Today, I want to take my OL6.1 with UEK setup and convert the root ext4 partition to btrfs.

The cool thing is that btrfs actually lets you do that, there's a tool called btrfs-convert which takes a volume as an argument and then converts ext[2,3,4] to btrfs and leaves the original ext[2,3,4] as a snapshot so you can even go back to it if you want to.

In order to do this I did the following : - prepared my initrd to have btrfs built in.

At this point you will see your system is not registered to any Red Hat subscription packages.
