Naturally there are a few that I created myself. But I am surprised by the number of files that exist on one of my fedora systems, files that did not arrive as part of an rpm. #find / -type f -print|grep -v '^/proc/'|while read file; do rpm -qf "$file" >/dev/null || echo "$file"; done > notinrpm wc -l notinrpm 1521 notinrpm Let's take an example: #rpm -qf /usr/share/firstboot/modules/language.pyc file /usr/share/firstboot/modules/language.pyc is not owned by any package #file /usr/share/firstboot/modules/language.pyc /usr/share/firstboot/modules/language.pyc: python 2.4 byte-compiled # stat /usr/share/firstboot/modules/language.pyc File: `/usr/share/firstboot/modules/language.pyc' Size: 8618 Blocks: 32 IO Block: 4096 regular file Device: 302h/770d Inode: 7365629 Links: 1 Access: (0644/-rw-r--r--) Uid: ( 0/ root) Gid: ( 0/ root) Access: 2007-11-17 20:43:55.000000000 -1000 Modify: 2007-06-25 12:45:32.000000000 -1000 Change: 2007-06-25 12:45:32.000000000 -1000 # ls -la /usr/share/firstboot/modules/language.pyc -rw-r--r-- 1 root root 8618 Jun 25 12:45 /usr/share/firstboot/modules/language.pyc Could this have been left behind when I erased some package? If not, where the heck did it come from? any way I can find out? When I google that filename I get one hit only, an ancient reference to FC1. # md5sum /usr/share/firstboot/modules/language.pyc 98449dfce4aa4b36c67a52e1a1f6dac6 /usr/share/firstboot/modules/language.pyc Hmm, wonder if you can get a result from googling an md5 sum. Not this one, at least. I have two rpms related to firstboot installed (well, two with 'firstboot' in the name), neither has anything named 'language' in it: # rpm -qa|grep firstboot firstboot-tui-1.4.23-1 firstboot-1.4.23-1 # rpm -q --filesbypkg firstboot|grep language # rpm -q --filesbypkg firstboot-tui|grep language Should I be getting paranoid at this point (or rather, allowing my pre-existing paranoia free range)?
