Next up in our series of a2k17 hackathon reports is this one from Antoine Jacoutot, who writes:
For once I did not try and plan anything for this hackathon because I wanted to
take the time to think over few things and talk with a few fellow developers.
First stuff I started to work on was syspatch(8), our upcoming "binary" patch
tool. Besides a few simplication in the code, we are now running all network
related actions as well as crypto verification as a separate unprivileged user
(_syspatch) just like our installer does.
We had a somewhat lengthy discussion with deraadt@ and rpe@ about how we wanted
our tools to use a common place to know where to fetch the operating system
components: we settled on having an /etc/installurl file (created by the
installer if the system is installed through an official mirror) that would only
include a mirror top level URL.
syspatch(8) is already using it to fetch the patches and so is the installer to
be able to display your "favorite" mirror. pkg_add(1) will come next.
On another topic, I kept working on a small yet important rc.d(8) improvement:
be able to catch hanging daemons at startup, be able to catch "bg" (`&') daemons
failure and eventually get rid of the rc_bg variable altogether (less knobs). I
started this work in Cambridge and I think it's now ready to be committed. While
the diff ended up being relatively small it does change how the rc.d "start"
action works and as such I'm waiting for the 6.2 release cycle to begin before
putting it in.
When I was starting to feel tired, it was the time for updating a few ports here
and there... business as usual.
I also took some time to enhance my AWS AMI creation script so that the image
matches a standard OpenBSD installation. It now creates a 4G image, with all
standard partitions except the ones used to build (/usr/obj and /usr/src).
i.e. /, /tmp, /var, /usr, /usr/X11R6, /usr/local and /home
The size are the minimal advised by the autopartition disklabel(8) (no need to
over provisionon these on Cloud instances) except for /var/ which has been
extended a bit to store upcoming syspatch(8) rollback tarballs. If you need more
disk, you can easily extend the underlying EBS (or even add one) and either add
a partition or growfs(8) /home.
Other than that, I really enjoyed meeting Shelob and the Dinosaurs
Thanks a lot to dlg@, jmatthew@ and the OpenBSD Foundation for making this event
