Subject: [PATCH] gopher: Add concept of tag-sorted notes

I've been musing about this for a while -- a simple plaintext "second
brain". Nothing fancy, but categorized notes that are easily version
controlled, edited, and servable for others to see.

So here's the combo of my favorite tech:

* version control -- git, of course
* edited -- $EDITOR
* servable -- why not try gopher?

+OpenBSD on Linode
+=================
+Tues Sept 21, 2021
+
+tags: openbsd
+
+I'm a huge fan of OpenBSD. The simplicity of the system, the cohesive
+feel it has, the proactive stance on security... The only problem?
+My preferred cloud provider (Linode) doesn't support it!
+
+Fortunately there's a comprehensive post on the Linode forum of how to
+do it [1].
+
+I wanted to document it here in case said post ever goes away.
+
+1. Create a New Linode (any OS will do)
+2. Once booted, shut it down
+3. Under the "Storage" tab delete the ext4 partitions
+4. Create two new disks, both "Raw" format:
+   - One labeled "install", 1GB (could do less)
+   - One labeled "os", the rest of the space
+5. Boot in "Rescue" mode
+6. In the serial console, wget the minirootXX.img
+   - Check the sha256 against the SHA256 file
+   - Check the signature using signify (on a different machine that
+     has signify)
+7. Find the install disk with `lsblk`
+8. Flash the img using: `dd if=minirootXX.img of=/dev/sdX bs=1M`
+9. In the Configurations tab, create a new one:
+   - Full Virtualization
+   - Select a Kernel > Direct Disk
+   - /dev/sda - os
+   - /dev/sdb - install
+   - boot from sdb
+10. Reboot into configuration, install OpenBSD from serial console
+11. Halt/shutdown, and change configuration to boot from sda
+12. Rejoice!
+
+NOTE: if you skip the "Direct Disk" kernel step, it boots a Linux
+kernel and tries to load the img... it panics every time!
