NAME
uts_namespaces - overview of Linux UTS namespaces
DESCRIPTION
UTS namespaces provide isolation of two system identifiers: the host-
name and the NIS domain name. These identifiers are set using sethost-
name(2) and setdomainname(2), and can be retrieved using uname(2),
gethostname(2), and getdomainname(2). Changes made to these identi-
fiers 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.
