debconf

[http://dummy.us.eu.org/robert (Robert)]

Today, I discovered debconf.  I didn't realize that it was a "shadow"
configuration database for Debian.  I discovered this when I spent almost
all yesterday moving SSD and hard drives from my wife's old computer (fan
died) to a new computer, and had trouble getting it to boot into Linux
again.  (Apparently, the drive that grub-install uses is cached in
debconf, and that, besides the fact that "/boot/efi" was mounted to the
wrong drive, caused me hours of grief.)
