I am trying to find out 1) how did I get /usr/src/.linux-versions? 2) who/what is using it? 3) whose responsible to fill in its contents? [02:27:36 /tmp]$ dpkg -S /usr/src/.linux-versions dpkg: /usr/src/.linux-versions not found. [02:27:52 /tmp]$ cat /usr/src/.linux-versions # This is a list of the current versions of Linux kernel sources or # kernel header packages on the system. [02:29:41 /tmp]$
