Re: [Xen-devel] [PATCH] xen/tools: Introduce QNX IFS loader

[Artem Mygaiev <artem.mygaiev@xxxxxxxxxxxxxxx>]

âOh, then we stick to libxc GPL license ensuring that no Apache 2 code gets in from us. QNX doesnt really enforce using some specific license in loader; for example it is possible to use grub (GPL) on x86... Oleksandr will have to re-submit patches

Yeah but, AFAIUI, the problem here is that it is *not* ok to have
Apache2 licensed code in libxc... :-(
