Hi Arvin,

I noticed that openSUSE buildservice now provides debs for ubuntu as
well. I can't seem to find a way to add it to apt source list though,
using the usual line

deb uri distribution [component1] ....

Is there a howto somewhere, or is it
download-all-debs-manually-and-install-with-dpkg for now?

Thanks,

=46ajar

You can use these commands:

echo 'deb http://download.opensuse.org/repositories/filesystems:/snappe=
r/Debian_6.0/ /' >> /etc/apt/sources.list

apt-get update
apt-get install snapper

I didn't know you could use that format :D Just tested it, and it
works, although the command I use is

echo 'deb http://download.opensuse.org/repositories/filesystems:/snapper/Debian_6.0/
/' | sudo tee /etc/apt/sources.list.d/opensuse-snapper.list

>
> apt-get update

That got me the error

W: GPG error: http://download.opensuse.org  Release: The following
signatures couldn't be verified because the public key is not
available: NO_PUBKEY 2DA6FAF4175BFA4E

easily fixed though, using

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 2DA6FAF4175BFA4E

... and then another apt-get update after that.


> apt-get install snapper

That result in a warning

WARNING: The following packages cannot be authenticated!
  libsnapper snapper
Install these packages without verification [y/N]?

Did the package creation process somehow ommit signing process,
perhaps? Or is there something else I missed?

Anyway, I got snapper-0.0.10-0 installed now, but having a small
problem. I use different subvolumes for multiple directories. For
example, /home and /data. Creating the config for both results in an
error

$ sudo snapper list-configs
Config | Subvolume
-------+----------
$ sudo snapper create-config /home
$ sudo snapper create-config /data
Creating config failed (config already exists).
$ sudo snapper list-configs
Config | Subvolume
-------+----------
root   | /home

How can I create config for /data or other directories (other than
manually creating the config file and .snapshots directory)?

This should do it:

sudo snapper -c home create-config /home
sudo snapper -c data create-config /data

The reasons for the extra "-c <name>" is that you have to
tell snapper, which name to choose for the configuration
you want to create. This name is the one you can reference
in future actions such as create/modify/delete.

Great! That works, thanks.

Is there an oposite of create-config, i.e. delete for just one subvolume?
delete-config seems to delete everything (configs for all subvolume
and all snapshots).

Also, one minor detail, I noticed that the cron configuration file is
/etc/sysconfig/snapper. It should be /etc/default/snapper in
ubuntu/debian.

delete-config only deletes one config. Otherwise that is a bug.

Thanks for the hint.
