I have been looking for a better distro to install on my beaglebone black with a better supported build environment. I originally tried gentoo but just pulling in updates fried the sdcard.

Void seems to be just what I'm looking for. Flashing void went without a hitch, so I setup my user account, filesystems, and etc...
After installing some core binary utilities I decided to see how the source based package management went.

    $ git clone git://github.com/voidlinux/void-packages.git
    $ cd void-packages
    $ ./xbps-src binary-bootstrap
I then tried:
$ sudo ./xbps-src pkg aircrack-ng
The result originally complained about the musl repos, since this isn't a musl build environment I just commented them out in repos-remote.conf
So then the result I am getting is:
$ [*] Updating `http://repo.voidlinux.eu/current/armv7l-repodata' ...
$ [*] Updating `http://repo.voidlinux.eu/current/nonfree/armv7l-repodata' ...
$ ERROR unshare (Invalid argument)
Any pointers or advice? Are there any logfiles I can check?
Thanks in advance.
