/.cache directory

[Avinash Sonawane <rootkea@gmail.com>]

Hello!

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...

$ ls -la /
total 76
drwxr-xr-x  19 root root  4096 Sep 23 12:17 .
drwxr-xr-x  19 root root  4096 Sep 23 12:17 ..
lrwxrwxrwx   1 root root     7 Sep 15 06:58 bin -> usr/bin
drwxr-xr-x   4 root root  4096 Sep 23 12:18 boot

drwxr-xr-x 160 root root 12288 Sep 25 20:34 etc
...
