Hardened browser updater filled up my disk by following symlink
I tried to upgrade from hardened-6.0a2 to a3 with the built-in updater. It sat there for many minutes making no obvious progress. Eventually I killed it and found its partition was full. I don't think it showed me an error about that.
What happened was that the "download" directory in the profile was a symlink to a larger partition. So it tried to copy ~1TB of downloaded files to my /home partition that was only 100GB. It should copy symlinks as links and not dereference them.
