uts_namespaces(7) Miscellaneous Information Manual uts_namespaces(7)
uts_namespaces - overview of Linux UTS namespaces
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.
