Using
mkrs
to
Create
a
Reco
v
ery
System:
The
mkrs
command
constructs
a
reco
v
ery
system
on
remov
able
media
(or
a
formatted
hard
disk
driv
e).
If
a
system
later
b ecomes
un
b o otable
due
to
a
corrupt
ro
ot
disk,
then
y
ou
can
b o ot
y
our
system
from
the
reco
v
ery
tap
e.
Once
b o oted
on

reco

y
ou
can
then

Some
Options
for
mkrs
Note
The
-s
option
is
necessary
for
building
Series
700
DDS-format
tap
e
reco
v
ery
systems.
If
enough
free
disk
space
is
a
v
ailable
in
/usr/tmp
(typically
10-20Mb),
the
-q
option
can
b e
used
to
make
mkrs
create
an
image
of
the
reco
v
ery
system
in
this
directory
b efore
cop
ying
it
to
the
reco
v
ery
media.
This
option
generally
sa
v
es
a
great
deal
of
time
due
to
reduced
seeking
on
non-random-access
reco
v
ery
media
(cartridge
tap
e
and
DDS-format).
Note:
for
DDS-format
tap
e
reco
v
ery
systems,
the
-q
option
is
assumed.
When
creating
a
DDS-format
reco
v
ery
system
for
a
small
memory
w
orkstation
(8Mb
or
less),
the
-s
option
should
b e
used
to
sp ecify
that
a
smaller
set
of
les
b e
placed
on
the
reco
v
ery
system.
