program
lo

for

alid
k
ernel
les
from
whic
h
to
b o ot
HP-UX.
As
it
lo
cates
v
arious
k
ernel
les,
it
creates
a
list
of
them
and
displays
them
on
the
screen
in
the
order
in
whic
h
it
found
them.
If
y
ou
are
b o oting
in
attended
mo
de
(ha
ving
pressed
the
space
bar
do
wn
after
the
\HIL"
message
indicated
that
the
k
eyb oard
w
as
active),
this
list
remains
on
the
screen
and
y
ou
ha
v
e
a
c
hance
to
select
from
the
list.
If
y
ou
are
b o oting
in
unattended
mo

the
system
will
immediately
select
the
rst
k
ernel
in
the
list.
T

b e
sure
it
is
the
one
y

t,
y
ou
will
need
to
make
sure
that
y
our
k

is
the

one
the
secondary

program
will
encoun
ter.
Step
4:
HP-UX
Locates
a
Root
File
System
Because
the
k
ernel
le
nearly
alwa
ys
comes
from
the
same
device
as
the
le
system
that
will
b ecome
ro
ot
le
system
for
HP-UX,
the
device
should
b e
ready
and
a
v
ailable.
Step
5:
HP-UX
Begins
Running
This
is
the
p oint
where
HP-UX
takes
con
trol
of
y
our
system's
resources
and
b egins
its
startup
pro cedure.
HP-UX
starts
up
its
rst
pro cess:
a
pro cess
called
init .
init
pro cesses
the
le
/etc/inittab
to
kno
w
whic
h
pro cesses
it
should
run
based
on
what
run
lev
el
HP-UX
is
in.
In
particular,
there
are
pro cesses
called
\gett
ys"
whic
h
are
resp onsible
for
putting
login
prompts
on
terminals.
If
y
ou
do
not
see
a
login
prompt
at
a
terminal
where
y
ou
think
there
should
b e
one,
c
hec
k
to
b e
sure
/etc/inittab
has
an
en
try
for
the
getty
corresp onding
to
the
run
lev
el
HP-UX
is
curren
tly
in.
F
or
more
information
on
this,
see
Chapter
9,
\Problems
with
T
erminals,"
in
Solving
HP-UX
Pr
oblems
.
The
/etc/inittab
le
is
also
the
place
where
init
determines
whic
h
run
lev
el
to
initially
place
HP-UX
in.
As
init
pro cesses
inittab ,
it
executes
a
shell
using
the
script
/etc/bcheckrc
follo w
ed
b
y
a
shell
using
the
script
/etc/brc
and
nally
a
shell
using
the
/etc/rc .
The
functions
of
these
shell
scripts
are
describ ed
in
Chapter
2
of
the
System
A
dministr
ation
Conc
epts
.
Note
If
y
our
computer
is
part
of
an
HP-UX
cluster,
the
le
/etc/inittab
is
a
con
text
dep enden
t
le

Problems
could
o ccur
if
