	Silent boot means to almost completely remove all kernel and OpenRC messages on boot from your system. This may make it harder to debug issues when booting your computer, but it is also relatively <u>simple</u> to get back a verbose message boot, with this following wiki page guide.

	* [https://~~www~~.~~youtube~~.~~com~~/~~watch~~?v=~~HoltBFnu0yo~~ https://www.youtube.com/watch?v=HoltBFnu0yo~~] [1~~]		If you do not use a graphical display manager, you might want to clear screen when a login prompt appears. You can achieve it in several ways.

			First option is to use getty's INITSTR argument, which allows to send a string before getty's main output, and [https://en.wikipedia.org/wiki/ANSI_escape_code#Control_Sequence_Introducer_commands escape codes] to clear screen:

			{{cat\|/etc/inittab\|...
			tty1::respawn:/sbin/getty -I '\033[2J\033[H' 38400 tty1
			...}}

			Alternatively, you can install [https://pkgs.alpinelinux.org/packages?name=agetty agetty], which clears screen by default, and modify <code>/etc/inittab</code> to use it:

			{{cat\|/etc/inittab\|...
			tty1::respawn:/sbin/agetty 38400 tty1
			...}}
