.Sh DESCRIPTION
|
|
.Pa /boot/sortix.bin
|
|
is the operating system
|
|
.Nm kernel .
|
|
It initializes and manages the hardware to provide a multitasking computing
|
|
environment.
|
|
The kernel is a
|
|
.Xr multiboot 7
|
|
compatible executable loaded by the bootloader along with a companion
|
|
.Xr initrd 7
|
|
that contains a userland.
|
|
.Pp
|
|
The kernel extracts the initrd into the initial kernel memory root filesystem.
|
|
The specified
|
|
.Ar init
|
|
program is invoked with the given arguments, defaulting to the
|
|
.Xr init 8
|
|
at
|
|
.Pa /sbin/init
|
|
if
|
|
.Ar init
|
|
is not specified.
|
|
If the
|
|
.Nm init
|
|
is to receive any argument starting with a dash, first pass the
|
|
.Fl \-
|
|
delimiter to stop kernel option parsing.
|
|
The computer is powered off if the
|
|
.Nm init
|
|
process exits 0, rebooted if it exits 1,
|
|
halted with an complaint about an
|
|
.Nm init
|
|
fatality if it exits 2, and halted with a complaint about an unexpected exit code
|
|
otherwise.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width "12345678"
|
|
.It Fl \-no-random-seed
|
|
Don't warn if no random seed file was loaded by the bootloader (usually from
|
|
.Pa /boot/random.seed ) .
|
|
This option is useful for live environments where this situation is unavoidable.
