# BENTOO-DIVERGENCE: INHERIT - shell-completion, the successor eclass that
# covers zsh and fish alongside bash; ::gentoo still inherits
# bash-completion-r1. newbashcomp below comes from it either way.

# BENTOO-DIVERGENCE: metadata.xml - a <longdescription>, an upstream <bugs-to>,
# and a longer description of the libvirt flag. The flag text is not decoration:
# ::gentoo says "Build plugin for kvm", which stopped being true when the kvm2
# driver moved into the binary and reached libvirt through dlopen (see the
# DEPEND tag above). The description had to follow the dependency.

# BENTOO-DIVERGENCE: DEPEND - app-emulation/libvirt is in RDEPEND only, where
# ::gentoo has it in both. The reason is below: nothing libvirt-related is
# needed to COMPILE. One atom moved between axes, so it shows up as a
# divergence on the axis it left as well as the one it landed on.
# Since 1.38 the kvm2 driver is linked into the minikube binary itself
# (pkg/minikube/registry/drvs/kvm2) and reaches libvirt through dlopen: the
# Makefile builds with -tags libvirt_dlopen, which selects "#cgo LDFLAGS: -ldl"
# instead of "#cgo pkg-config: libvirt" in libvirt.org/go/libvirt.  Nothing
# libvirt-related is needed to compile, so the dependency is runtime-only --
# without it dlopen("libvirt.so.0") fails and only the kvm2 driver is lost.
RDEPEND="libvirt? ( app-emulation/libvirt:=[qemu] )"

# BENTOO-DIVERGENCE: BDEPEND - no dev-go/go-bindata, for the reason below.
# go.mod says "go 1.25.0"; the eclass only floors go at its own default, and
# portage raises a QA notice for the gap.  dev-go/go-bindata is gone from here:
# the Makefile stopped invoking it, and nothing outside a comment and one
# skip-path regex mentions bindata any more.
