I'm using Debian GNU/Linux 13 (trixie) which I recently installed. I
noticed that there is a directory named ".cache" at root level. It
seems to be created at the time of installation. What is it? Who has
created it? Seems to be a bug in some package which has created it...

Hi, probably, it was created by an installer script. By going through the
log (files) of dpkg, it may be possible to narrow down the list of candidate
packages using the creation time of /.cache.
Why do you assume it was done by an "installer script"? Based on the
timestamps, it looks like it was about 10 minutes after the installation
created the /bin symlink, which is either short enough that it *could*
have happened at a late stage of the installation, or long enough that
it *could* have been done by Avinash shortly after the installation.
