config GENTOO_LINUX

	bool "Gentoo Linux support"

	default y

	help

		In order to boot Gentoo Linux a minimal set of config settings needs to

		be enabled in the kernel; to avoid the users from having to enable them

		manually as part of a Gentoo Linux installation or a new clean config,

		we enable these config settings by default for convenience.

		See the settings that become available for more details and fine-tuning.

config GENTOO_LINUX_UDEV

	bool "Linux dynamic and persistent device naming (userspace devfs) support"

	depends on GENTOO_LINUX

	default y if GENTOO_LINUX

	select DEVTMPFS

	select TMPFS

	select UNIX

	select MMU

	select SHMEM

	help

		In order to boot Gentoo Linux a minimal set of config settings needs to

		be enabled in the kernel; to avoid the users from having to enable them

		manually as part of a Gentoo Linux installation or a new clean config,

		we enable these config settings by default for convenience.

		Currently this only selects TMPFS, DEVTMPFS and their dependencies.

		TMPFS is enabled to maintain a tmpfs file system at /dev/shm, /run and

		/sys/fs/cgroup; DEVTMPFS to maintain a devtmpfs file system at /dev.

		Some of these are critical files that need to be available early in the

		boot process; if not available, it causes sysfs and udev to malfunction.

		To ensure Gentoo Linux boots, it is best to leave this setting enabled;

		if you run a custom setup, you could consider whether to disable this.

config GENTOO_LINUX_PORTAGE

	bool "Select options required by Portage features"

	depends on GENTOO_LINUX

	default y if GENTOO_LINUX

	select CGROUPS

	select NAMESPACES

	select IPC_NS

	select NET_NS

	select PID_NS

	select SYSVIPC

	help

		This enables options required by various Portage FEATURES.

		Currently this selects:

		CGROUPS     (required for FEATURES=cgroup)

		IPC_NS      (required for FEATURES=ipc-sandbox)

		NET_NS      (required for FEATURES=network-sandbox)

		PID_NS		(required for FEATURES=pid-sandbox)

		SYSVIPC     (required by IPC_NS)

		It is highly recommended that you leave this enabled as these FEATURES

		are, or will soon be, enabled by default.

config GENTOO_LINUX_INIT_SCRIPT

	bool "OpenRC, runit and other script based systems and managers"

	select BINFMT_SCRIPT

	select CGROUPS

	select EPOLL

	select FILE_LOCKING

	select INOTIFY_USER

	select SIGNALFD

	select TIMERFD

	help

		The init system is the first thing that loads after the kernel booted.

		These config settings allow you to select which init systems to support;

		instead of having to select all the individual settings all over the

		place, these settings allows you to select all the settings at once.

		This particular setting enables all the known requirements for OpenRC,

		runit and similar script based systems and managers.

		If you are unsure about this, it is best to leave this setting enabled.

		it also enables suggested optional settings, as the package suggests to.
