If you want to use our binary packages and setup unikernels, follow [these instructions](https://robur.coop/Projects/Reproducible_builds). The unikernels are statically linked executables where the execution target is independent of the build platform - so even if they're compiled on a FreeBSD system they can be run on a Linux or OpenBSD host. Many are executed using a [solo5](https://github.com/solo5/solo5) tender. The filename suffix of the unikernel binary indicate the expected execution environment: - `.hvt`: hardware virtualized - requires `solo5-hvt` ([Linux KVM](https://www.linux-kvm.org/page/Main_Page), [FreeBSD BHyve](https://wiki.freebsd.org/bhyve), [OpenBSD VMM](https://man.openbsd.org/vmm)), - `.spt`: sandboxed process - requires `solo5-spt` (Linux with seccomp), - `.xen`: Xen PVH virtual machine (on a Xen or QubesOS host), - `.virtio`: any virtio environment (qemu, GCE, KVM, BHyve), - `.muen`: on [muen](https://muen.sk). A persistent link to the latest successful build is available as `/job/*jobname*/build/latest/`. Each build can be reproduced with [orb](https://github.com/robur-coop/orb/). The builds are scheduled and executed daily by [builder](https://github.com/robur-coop/builder/). This web interface is [builder-web](https://git.robur.coop/robur/builder-web/). Read further information [on our project page](https://robur.coop/Projects/Reproducible_builds).
