## Prerequisites
|
|
|
|
The following packages are needed to run bocker.
|
|
|
|
* util-linux >= 2.25.2
|
|
* btrfs-progs
|
|
|
|
Because most distributions do not ship a new enough version of util-linux you will probably need grab the sources from [here](https://www.kernel.org/pub/linux/utils/util-linux/v2.25/) and compile it yourself.
|
|
|
|
Additionally `/var/bocker` needs to be on a btrfs filesystem.
|
|
|
|
For ease of use a Vagrantfile is included which will build the needed environment.
|
|
|
|
