Java is required to run yui-compressor which is in turn required to build ajenti. The one available in aur is horribly slow and comes prebuilt from pypi.Anyway, the package is available here: $this->bbcode_second_pass_code('', 'https://github.com/moonman/PKGs/blob/master/ajenti')
This package should work on any architecture (arm, armv6h, armv7h).
To start/enable:
$this->bbcode_second_pass_code('', 'systemctl start/enable ajenti')
Access at: http://<ip>:8000
User: root Pass: admin
For the curious, if you want to build it yourself, everything required is here.
