The initramfs has (basically) one purpose in life -- getting the rootfs +mounted so that we can transition to the real rootfs. This is all driven off of device availability. +Therefore, instead of scripts hard-coded to do various things, we depend on udev to create device +nodes for us and then when we have the rootfs's device node, we mount and carry on. This helps to +keep the time required in the initramfs as little as possible so that things like a 5 second boot +aren't made impossible as a result of the very existence of an initramfs. It's likely that we'll +grow some hooks for running arbitrary commands in the flow of the script, but it's worth trying +to resist the urge as much as we can as hooks are guaranteed to be the path to slow-down. Also, +there is an attempt to keep things as distribution-agnostic as possible. +" +HOMEPAGE="https://dracut.wiki.kernel.org/" + +UPSTREAM_DOCUMENTATION=" + https://www.kernel.org/pub/linux/utils/boot/dracut/dracut.html [[ description = [ Manual ] lang = en ]] +" + +LICENCES="GPL-2" +SLOT="0" +MYOPTIONS="" + +DEPENDENCIES=" + build: + app-doc/asciidoc + app-text/docbook-xml-dtd:4.5 + dev-libs/libxslt + dev-util/elfutils + sys-apps/kmod[>=23] + run: + app-shells/bash[>=4.0] + virtual/pkg-config + sys-apps/coreutils[xattr] + sys-apps/util-linux[>=2.21] + test: + app-shells/dash + recommendation: + sys-process/procps [[ + description = [ Required by the base module for pidof if not using busybox ] + ]] + suggestion: + app-arch/pigz [[ + description = [ Support parallel (de)compression via pigz ] + ]] + app-crypt/gnupg [[ + description = [ Add support for GPG-encrypted keys to the crypt module ] + ]] + app-shells/dash [[ + description = [ Support for dash as the initramfs shell ] + ]] + net-fs/cifs-utils [[ + description = [ Required by the CIFS module for rootfs on CIFS ] + ]] + net-fs/nfs-utils [[ + description = [ Required by the NFS module for rootfs on NFS ] + group-name = [ dracut-nfs-module ] + ]] + net-misc/open-iscsi [[ + description = [ Support for rootfs on iSCSI ] + ]] + net-nds/rpcbind [[ + description = [ Reguired by the NFS module for rootfs on NFS ] + group-name = [ dracut-nfs-module ] + ]] + sys-boot/plymouth [[ + description = [ Provides boot splash support ] + ]] + sys-fs/btrfs-progs [[ + description = [ Support for multi-device btrfs filesystems ] + ]] + sys-fs/cryptsetup [[ + description = [ Support for an encrypted rootfs using dmcrypt ] + ]] + sys-fs/lvm2 [[ + description = [ Support for LVM volumes and device-mapper partitions for various modules ] + ]] + sys-fs/multipath-tools [[ + description = [ Support for rootfs on multipath devices ] + ]] + net-misc/bridge-utils [[ + description = [ Required by the network boot module for brctl ] + group-name = [ dracut-network-module ] + ]] + net-misc/dhcp [[ + description = [ Required by the network boot module for dhclient ] + group-name = [ dracut-network-module ] + ]] + net-misc/iputils [[ + description = [ Required by the network boot and debug module for arping and ping ] + group-name = [ dracut-network-module ] + ]] + sys-apps/iproute2 [[ + description = [ Required by the network boot module for ip ] + group-name = [ dracut-network-module ] + ]] + sys-apps/keyutils [[ + description = [ Required by the masterkey, ecryptfs and integrity modules to decrypt keys ] + ]] + sys-apps/net-tools [[ + description = [ Required by the iSCSI and debug module for hostname and netstat ] + ]] + sys-libs/libcap [[ + description = [ Required by the caps module for initramfs which drops capabilities ] + ]] + virtual/syslog [[ + description = [ Support for logging to a remote server with the syslog module ] + ]] +" + +# As broken as it gets - the tests even signal failure when they're just checking +# for the file system type +RESTRICT="test" + +# TODO +# - Some modules need additional/unpackaged dependencies and testing. +# See module-info.sh or module-setup.sh in the module directory, + + +DEFAULT_SRC_PREPARE_PATCHES=( + "${FILES}"/0001-base-dracut-lib.sh-dev_unit_name-guard-against-dev-b.patch + "${FILES}"/0002-systemd-initrd-add-initrd-root-device.target.patch + "${FILES}"/0003-50-dracut.install-use-bin-bash-shebang.patch + "${FILES}"/0004-redcore-change-default-initramfs-name.patch + "${FILES}"/0005-dracut-044-bash-4.4.patch + "${FILES}"/0006-dracut-044-preserve-xattrs-when-copying.patch + "${FILES}"/0007-dracut-044-backport-fix-for-microcode-loading.patch + "${FILES}"/0008-dracut-044-ext4-and-f2fs-need-crc32X-too.patch + "${FILES}"/0009-sort-fixup-creating-early-microcode.patch +) + +DEFAULT_SRC_CONFIGURE_PARAMS=( + --bashcompletiondir=/usr/share/bash-completion/completions + --systemdsystemunitdir="${SYSTEMDSYSTEMUNITDIR}" +) + +DEFAULT_SRC_INSTALL_PARAMS=( + prefix=/usr + libdir=/usr/$(exhost --target)/lib + sysconfdir=/etc +) + +dracut_src_prepare() { + default + + edo sed -i -e "s:HOST-\(strip\):$(exhost --target)-\1:g" dracut.sh + + # Dracut's "Test Matrix" requires root privileges and are excessive. + # This disables them and only runs the syntax check with dash. + edo sed -i -e '/$(MAKE) -C test check/d' Makefile + + # Fix libdir. + edo sed -i -e "s:/lib\(/kernel/install.d\):/$(exhost --target)/lib\1:" Makefile + + # Remove modules that are not compatible with Exherbo. + edo rm -r modules.d/45ifcfg +} + +dracut_src_install() { + export systemdsystemunitdir="${SYSTEMDSYSTEMUNITDIR}" + + default + + insinto /usr/share/doc/${PNVR}/html/ + doins dracut.html dracut.png + + keepdir /etc/dracut.conf.d + keepdir /usr/$(exhost --target)/lib/dracut/dracut.conf.d + + insinto /etc/logrotate.d/ + newins dracut.logrotate dracut +} + |
