When removing the Linux check, playonlinux starts. However, when trying to install a windows program (7zip), it downloads a linux version of wine. This (obviously) doesn't work. Maybe recoding playonlinux to download a custom GNU/kfreeBSD version of wine would help, but I can understand that this project isn't on the front burner.
Tldr: It doesn't do anything useful. -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
