Using

to
Create

System:
The
mkrs

driv
e.
If y
our system
later
b
ecomes
un

then
you
can

Some
Options
for
mkrs
If
enough
free
disk
space
is
a
v
ailable
in
/usr/tmp
(typically
10-20Mb), the
-q
option
can
b
e
used
to
mak
e
mkrs
create
an
image
of
the
reco
v
ery
system
in
this
directory
before
it
copies
it
to
the
reco
v
ery
medium.
This
option
generally
sa
v
es
a
great
deal
of
time
due
to reduced
seeking
on
non-random-access
reco
v
ery
medium
(cartridge
or
DDS
tap
e).
F
or
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.
See
