I begin to hate this hard disk. It got stuck once again, causing a several hour downtime. When it came back, the filesystem was partially corrupted. I fixed it. Then I realized that while fixing it, I got rid of a few files. Random config and data files disappeared. It took me some time to figure out what was missing. I recovered missing bits from original software packages and backups. It looks like it works fine now, but if you notice anything strange – please let me know.
My appologies for the inconvenience.
