OpenRiot v7.9.20 — The One Where 1.8TB Became 1 Byte

“1.5 TB is a lot of bytes. Just one of them is not.” — The OpenRiot Crew, discovering that ParseDriveSize was splitting on the space and reading only the last character

---

Release Overview

v7.9.20 ships the Utilities submenu and integrates Migrate — a pure-Go backup/restore tool — into the OpenRiot ecosystem. The main Rofi launcher gets a cleanup: WiFi, Monitor, Drive Manager, Backup & Restore, Benchmark, System Monitor, and System Settings all move to Utilities, keeping the main menu clean.

Migrate itself required six surgical fixes to work on OpenBSD. The most spectacular: a 1.8 TB USB drive was detected as 1 byte because FormatBytes("1.8 TB") outputs with a space, but ParseDriveSize takes the last character as the unit. "1.8 TB" → strip space → "1.8TB" → last char = "B" → multiplier = 1 → int64(1.8 * 1) = 1 byte. You need at least 1.8 TB of total drive capacity.

Utilities Submenu

Cleanup of the main Rofi launcher. Gone: WiFi, Monitor, Drive Manager, Benchmark, System Monitor, System Settings. They now live in a @submenu:utilities:

Utilities
├── WiFi Config (openriot --nmtui)
├── Monitor Config (openriot --resolution-tui)
├── Drive Manager (openriot --disk)
├── Backup & Restore (migrate)
├── Drive Benchmark (openriot --disk)
├── System Monitor (btop)
└── System Settings (xfce4-settings-manager)

OpenRiot Settings stays in the main menu where it belongs.

Each utility gets a for_window floating rule in i3 and an icon in icons.toml for Polybar workspace labels. openriot_migrate uses the archive icon 󰆼 because nothing says “system backup” like a zipped box.

Migrate OpenBSD Fixes

The backup/restore tool needed six fixes to run on OpenBSD:

Issue	Root cause	Fix
Build failure	Brace structure mangled	Rewrote if block
	in ui.go
Build failure	Missing imports	Added drives and platform
		packages to ui.go
LUKS warning	Rendered on OpenBSD	runtime.GOOS != "openbsd"
	where LUKS doesn’t exist	guard
1 byte drive	FormatBytes outputs	Strip spaces, extract trailing
	"1.5 TB" but	alphas as unit (not last char),
	ParseDriveSize reads	take first char for multi-letter
	last char as unit ("B")	units ("TB" → "T")
Slow backup	.cargo, .rustup,	Added to GetHomeBackupExclusions
	.npm, .go/pkg/mod,	— all rebuildable with cargo,
	.cabal, .stack,	rustup, npm, go install
	.m2 have tons of
	rebuildable files
No progress info	Spinner with no ETA	Added Elapsed/ETA to
		ProgressUpdate, renders in
		renderProgress() as
		`“Total Time: 00:02:34
		Estimated Completion: 00:01:23”`

🗣️ Final Words

“1.8 TB. One tiny space. One teeny ‘B’. And suddenly your backup drive is smaller than a floppy.” — The OpenRiot Crew, on the difference between “1.8 TB” and “1 B”
