testing snapper f21 btrfs

[Neal Becker]

I have a default btrfs install of f21.

sudo btrfs subvolume list /
ID 257 gen 32476 top level 5 path root

I copied /etc/snapper/config-templates/default to 
/etc/snapper/config/default, and edited /etc/sysconfig/snapper to 
SNAPPER_CONFIGS="default"


BTW: there is NO documentation about this installed with the rpm, I'm not 
even sure I did this correctly.

snapper list-configs
Config  | Subvolume
--------+----------
default | /        

[nbecker@nbecker2 linearizer]$ sudo snapper -c default list
Type   | # | Pre # | Date | User | Cleanup | Description | Userdata
-------+---+-------+------+------+---------+-------------+---------
single | 0 |       |      | root |         | current     |         

So am I all set up to be able to use snapper to snapshot, rollback, etc?
I see rollback is supposed to be able to change the volume that is booted, 
but I'm afraid to try it.

Actually, you should be concerned about the lack of documentation.

If the package came with proper docs, you'd be able to tell by reading them.

The doc issue isn't my real concern.

What I want to know is, does my setup look OK?  Has anyone tried this?  Is 
it likely rollback would actually work?

Judging by the supplied file, it appears to be a list of snapper-config
files, but I agree it should be documented.

What's missing is a README.fedora that tells you what do do with 
/etc/sysconfig/snapper, which is fedora-specific I would think.

Didn't know about snapper, but after installing with yum I see man pages
for snapper and snapper-configs.
