Uname utility in *nix retrieves wonderful meta information about the machine. Where is this information stored?

The uname command is actually a front end for a system call that does the same thing. The kernel pretty much knows what it is. You can also see this information on, for example /proc/sysinfo.

Part of the utsname information is also accessible via

/proc/sys/kernel/{ostype, hostname, osrelease, version, domainname}

see uname man page

The kernel, mostly, where at least the hostname is usually read from /etc/hostname or a similar file during bootup.

The uname command retrieved informations are stored in etc/hostname that hostname file contains your machine name.

No. It contains only the hostname, no kernel related information. – Michael Nov 24 '12 at 10:22
