Bug#679334: debian-installer: at first boot: [warn] about /etc/mtab vs. /proc/mounts
this is a very minor glitch, might be in d-i's way of installing
packages, or a package's installation script might be a bit smarter.
[warn] Creating compatibility symlink from /etc/mtab to /proc/mounts. ... (warning).
I can't find those strings in sid, so it's presumably fixed already.
Filing anyway to avoid forgetting about it.
