From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Also check
ls -ld /
to view the permissions of/
itself. Sounds like whatever happened to boot also happened to the root. A quickchown root:root /
should make dbus happy. Don't recursively chown or chmod the root partition, that can result in a worse situation. Hopefully only/
and/boot
were affected.So that's why the wrong IDs came from. Technically the filesystem doesn't know about names, it knows about IDs, and software just look at
/etc/passwd
and/etc/groups
to go ID<>name./
should be 0755 (drwxr-xr-x). Boot, you can chown it all to root and 0755 for directories and 0644 for files safely. The reason you can't for the root is, you'll likely break executable state or SUID bits that sudo needs to be sudo.
