NAME 🖥️ uts_namespaces 🖥️
overview of Linux UTS namespaces
DESCRIPTION
UTS namespaces provide isolation of two system identifiers: the hostname and the NIS domain name. These identifiers are set using sethostname(2) and setdomainname(2), and can be retrieved using uname(2), gethostname(2), and getdomainname(2). Changes made to these identifiers are visible to all other processes in the same UTS namespace, but are not visible to processes in other UTS namespaces.
When a process creates a new UTS namespace using clone(2) or unshare(2) with the CLONE_NEWUTS flag, the hostname and domain name of the new UTS namespace are copied from the corresponding values in the caller’s UTS namespace.
Use of UTS namespaces requires a kernel that is configured with the CONFIG_UTS_NS option.
