Linux To Introduce The Ability To Set The Hostname Before Userspace Starts
While the hostname on Linux systems is widely relied upon for different applications, setting the hostname is usually left up to user-space by the init system at boot. However, should any user-space processes try to read the system hostname prior to it being set, it could lead to unintended results.
