I needed to write an iso image to a USB key, and the typical way is
with just dd(8), but I wanted a progress bar. A quick google later,
and I get:
pv -tpreb isoname | sudo dd of=/dev/sdd bs=1024
Which will write the iso image to the USB stick sdd, and give me a
progress bar, tell me how fast it is writing, and give me an eta when
Since there was a security part, I started with OpenBSD. One of the things I noticed quickly while doing my research is that while there is a lot of documentation, they do not really seem to care about making it easy for new folks to join the project, nor are the trying to support new-fangled hardware, like bootable USB drives. This strikes me odd, as FreeBSD has instructions (see 2.3.5).
Since I want to use pf, I am going to stay with OpenBSD for now.
