I would be wanting to mount filesystems read-only and try to copy data off to another disk, then reinstall on the disk with damaged disklabel and copy back, rather than relying on the existing filesystems long-term.

To be clear: having overwritten the starting 5GB of sd1c, but not of the underlying sd0c, you still have the CRYPTO volume on sd0c which you can attach with bioctl, right?

All the points you mention can be surely areas where mg can be improved, but you don't need to change the buffer data structure, its file handling, or how dot/mark works to implement vertical splits. You 'only' have to augment the way the display draws the windows (emacs parlance for splits) so that they can be arranged in a tree (currently it's a list IIRC) to accomodate for nesting horizontals and vertical splits. Actually, we could take inspiration from the vis text editor and only split either horizontally OR vertically which is simpler. Re-flowing a completely different story. mg could do reflowing without supporting vertical splits or have vertical splits without reflowing; much like how a better data structure could reduce the memory footprint or allow some unicode support but it's independent from (much) of the display logic.

I'd love to have vertical splits in mg as well, but the display logic needs some heavy work to accomodate for it. Take a look at display.c, it's written in a way to only handle horizontal splits. In fact, among the various micro emacs descendants almost no implementation support vertical splits :/ Not to say that's impossible for mg, just that it takes some non trivial work.

Asked ChatGPT 4 about contributing to OpenBSD, this was its reply
Contributing to the OpenBSD project or any other open-source project is a rewarding experience that allows you to learn, improve your skills, and give back to the community. Here are the steps and considerations to start contributing to the OpenBSD project as a developer: 1. Familiarize Yourself with OpenBSD: - Use OpenBSD, get to know its philosophy, its documentation, and its codebase. Understanding the system and the community's standards and expectations is crucial. 2. Join the Mailing Lists: - Sign up and participate in OpenBSD mailing lists, especially the tech mailing list where much of the development discussion happens. Be respectful, and learn from the discussions. 3. Identify Areas of Interest: - Identify areas within the project that interest you or where you see a need. It could be bug fixing, system tools, user applications, documentation, or driver development. 4. Learn the Coding Standards: - Familiarize yourself with OpenBSD's coding style and standards. Consistency in coding style is important in collaborative projects. 5. Start Small: - Start with small tasks such as bug fixing or improving documentation. These contributions are valuable and can help you become familiar with the contribution process. 6. Work on Bug Reports: - Look for bug reports, test existing bug reports, and provide feedback or solutions. The bug tracking system can be a good place to find where help is needed. 7. Create and Submit Patches: - If you have code contributions, create patches and submit them to the appropriate mailing list for review. Be prepared for feedback, and be open to making revisions to your contributions. 8. Respect Feedback: - Feedback is a valuable part of the open-source development process. It helps you learn and improve your contributions. 9. Follow Up: - Stay engaged, follow up on your contributions, and address any additional feedback or questions from reviewers. 10. Engage with the Community: - Engage with other developers, contribute to discussions, and attend OpenBSD events or meetups if possible. 11. Read OpenBSD's FAQ on Contributing: - OpenBSD has a FAQ section on how to contribute to the project. It is recommended to read through it to understand the expectations and processes. 12. Consider Becoming a Regular Contributor: - As you gain experience, consider becoming a regular contributor. With time and consistent, quality contributions, you might be invited to become a developer with commit access. Remember, contributing to open-source projects like OpenBSD is about more than just code. It's about being part of a community and working together to improve and advance the project.
Re: I nuked my filesystem
Thank you all for your replies. I needed to step away from my computer last night so I apologize for the terse email. sd0 is my physical hard disk with full disk encryption. I wrote a 5gb iso over the beginning of sd1c (my softraid volume). I rebooted. I installed openbsd on a separate drive, booted it, mounted the encrypted volume, and hopelessly ran scan_ffs. After reading Stuart's advice, I will attempt to reinstall the disklabel from scratch. I installed 7.2 on my second disk; the version I used to do the initial install. When I initially set up my disk, I used the auto partition defaults which left me with a 300gb /home directory. Later, I expanded the /home partition across the rest of the disk. When I recreate the disklabel, should I let it auto partition and then grow the file system like before? Or should I just set home to fill the rest of the disk?

Firstly your WN821N (an 11n NIC) won't support 11ac anyway. Newer wireless protocols aren't just "a mode" but a whole set of things are needed from the hardware and driver and 802.11 stack to support them - different radio modulation, features like frame aggregation, block ack, etc. >> FreeBSD already has code for 802.11n/HT support in their fork of >> the rtwn driver, which has significantly diverged over years. > > I will give FreeBSD a spin, although my preference is to run OpenBSD. I think that was a hint as to where to look if wanting to work on the OpenBSD driver for WN821N to support 11n. (11n will be a huge improvement over 11g - obviously not as good as a full 11ac implementation but still fairly usable - in large part due to the additional features rather than modulation).

Re-creating the disklabel is obviously the primary focus in these situations - the data which has been overwritten is gone if it's not backed up elsewhere, but non-overwritten stuff can potentially be recovered. Once piece of advice, which is sadly probably too late for this particular case, but very, very useful to know and remember for the future: * The kernel keeps it's working copy of the disklabel in memory. * If you know this in advance, what this means is that if you overwrite a raw disk device and realise what you've done, just keep cool. Immediately hit ^C, and invoke disklabel. Since you were dd'ing to a raw device, you were likely already logged in as root and doing other things related to partitioning, etc. Even if you've overwritten the boot and root partitions, things like ksh and the disklabel binary are likely in the buffer cache. If you can get in to disklabel and display the label for the trashed disk, then note it down somewhere, even if that means writing it down on paper. Having this information is the key to any recovery of data that was not overwritten.

With a typical softraid FDE setup, not going too far from the defaults, this likely means that the partition table, disklabel, root partition and swap on the softraid volume were overwritten, but other partitions might be ok if you can find them. If you don't have a copy of the disklabel stored away somewhere, current options are probably - port the scan_ffs ffs2 support from netbsd - hack things up so you can get something out of our scan_ffs as in https://marc.info/?l=openbsd-misc=167702020925723 (as shown in Matthew's mail, your initial target with either of these should be /var/backups/disklabel.sd1.* so you can restore it and skip scanning for other filesystems) - brute-force likely locations for /var (try on 1G boundaries) with the read-only mount approach from that mail - try to recreate disklabel from scratch (*if* you accepted auto partition defaults when installing, you might be able to recreate them by using disklabel from the same OpenBSD version as you used to install with auto-partitioning again, but the default sizes have changed over time, so that will only help if you know the version).

First you have to show what actually is left, i.e. what parts of the system are still available. Was sd1 a big /data disk such as /home, with the base system living elsewhere?
