The Makefile installs symbolic links by default, which actually worked at some point (not by design) with SELinux, but at least on recent kernel versions it doesn't anymore: override pasta (and pasta.avx2) with hard links. Otherwise, even if the links are labeled as pasta_exec_t, SELinux will "resolve" them to passt_exec_t, and we'll have pasta running as passt_t instead of pasta_t.

%description
|
|
passt implements a translation layer between a Layer-2 network interface and
|
|
native Layer-4 sockets (TCP, UDP, ICMP/ICMPv6 echo) on a host. It doesn't
|
|
require any capabilities or privileges, and it can be used as a simple
|
|
replacement for Slirp.
|
|
|
|
pasta (same binary as passt, different command) offers equivalent functionality,
|
|
for network namespaces: traffic is forwarded using a tap interface inside the
|
|
namespace, without the need to create further interfaces on the host, hence not
|
|
requiring any capabilities or privileges.
