Total: ∞ packages (0 good luck, 1 mistake)

I’d just like to put this out there for everybody…

  1. Make frequent backups. Maybe every month.
  2. Do not, under ANY circumstances, accidentally try to install Haiku to /dev/sda. Ever.

Now that the advice is out of the way, it’s story time!

Yesterday, I was trying to install Haiku to my 512MB flash drive, which, when I plugged it in, got assigned /dev/sdb. The Haiku build system was, at the time set to write to /dev/sda2 (my 3GiB Haiku partition). I deleted the “2” and went on with my business. I ran jam -q haiku-image to build it.
“Hmm, this is taking a while.”
“dd, wrote 134 MB to /dev/sda”
“/dev/sda?! WHAT?!”

It wrote 134 MB of 0x00s to the beginning of my hard drive, clobbering the bootloader, partition table, and the root filesystem of my Linux installation (/dev/sda1).

It also got to the “Populating Image” step, so it was happily chugging along writing a Be File System over my entire hard drive and filling it with Haiku data.

Programs still ran, not all the files on / were lost, and I was in a state of panic.
One reboot later confirmed the obvious – no more system. Also, no more files in /. The filesystem layout was in memory, and I should have taken the time to recover some of the data before I reformatted.

fsck told me that /usr was trashed.. /usr is like “Program Files” and more for Linux… Random data written in random places on a volume is… bad 😉
/ was definitely a goner…
/home somehow survived, guaranteeing that my 8 years-worth of data would stick around for a while longer!
Fortunately, I had backups from August 15th!
Unfortunately, they were from August 15th. That means 3 months worth of upgrades to do…

Restored / and /usr, some of /var (installed package database only), and went to work upgrading.

500 compiled and installed packages later (the last of which are still going) and Jesus is… Well, for the situation, I have to say he’s done pretty darn well. Kudos, me.

Once this is all done?


I think I need a NOS.
