¶4.Manifest(メタデータ)の作成

ebuildファイルを書き終えたらメタデータファイルであるManifestというファイルを作成します。 Manifestファイルにはソースコードの入ったtarballなどのチェックサムが保存してあるみたいです。

mkinitcpio-busyboxのManifestファイルは先ほど作ったシェルスクリプトを実行すれば作成されます。

(chroot) hc4Gentoo / # mkdir  /usr/local/portage/metadata/
(chroot) hc4Gentoo / # nano  /usr/local/portage/metadata/layout.conf
(chroot) hc4Gentoo / # cat /usr/local/portage/metadata/layout.conf
masters = gentoo

(chroot) hc4Gentoo / # ebuild /usr/local/portage/sys-kernel/mkinitcpio/mkinitcpio-34-r1.ebuild manifest
