First mount/umount of
#HAMMER2
on
#OpenBSD
A series of screencasts of hammer2 commands in OpenBSD, exploring everyday situations. Today we'll cover mount and umount. Soon I will publish a video (~6 min) applying a kernel patch + userland to get to the point in this video.

OpenBSD on Firecracker. 1.4 MB kernel, ~30 ms cold boot, no BIOS, no PCI, virtio-mmio only. Experimental port. Wrote up how to build the kernel, prep an FFS2 disk with vnd(4), and boot the thing from Linux.

i've been testing bt on an obsd snapshot ThinkPad X1 Nano, mainly for mouse/keyb use, is just for personal use. The learning experience has been incredible the OpenBSD codebase is exceptionally clean and insightful. HID (mouse/keyb) is still not reliable enough for daily use.

Kloset: the immutable data store
On the surface, plakar may appear as just another backup tool: it takes data and safely stores it until restoration is needed—essentially, a sophisticated version of the cp command.

The next version of Rust might be one of the most transformative to the Rust ecosystem due to support for up-casting of trait objects. This makes `Any` significantly more powerful and potent!
