Suppor t, Maintenance, and Patch Management
Admin CD, download the patches via the SuSE Maintenance Web and burn
the ISO file to a CD. Find instructions for the patch on the SuSE Maintenance
Web. This procedure has the great advantage that your Live CD is absolutely
up-to-date.
As soon as a new ISO file appears for the Live CD, you will be sent a new
Live CD, regardless of whether you have already downloaded the file. If
several ISO files appear within a short period of time, for example, because
several different security holes have been discovered at short intervals, you
will be sent the most recent Live CD to appear. Because it takes a number of
days to produce and send the CD, it would not make sense to send several
no longer up-to-date CDs.
Burning ISO Images with cdrecord
An ISO image is an “image” of a CD. This image can be mounted or burnt
to a CD. For reasons of security, you can only burn CDs in Linux as the user
root. Change to root with su. After entering the root password, check to
which bus the CD burner is connected with cdrecord -scanbus. This gen-
erates output containing something like:
...
scsibus0:
0,0,0 0) *
0,1,0 1) *
0,2,0 2) *
0,3,0 3) *
0,4,0 4) ’YAMAHA ’ ’CRW8824S ’ ’1.00’ Removable CD-ROM
0,5,0 5) *
0,6,0 6) ’TOSHIBA ’ ’DVD-ROM SD-M1201’ ’1011’ Removable CD-ROM
0,7,0 7) *
In this case, the CD burner was made by Yamaha. The numbers 0,4,0 specify
the target device. Your numbers may be different, depending on the configu-
ration. Make note of those numbers. To burn the ISO image to CD, enter the
following as the user root:
root@earth:~ > cdrecord -V dev=X,Y,Z speed=4 -eject
In our example, replace the place holders X, Y, and Z with the correct values,
noted earlier. The options here have the following meanings:
-V provides detailed messages
dev specifies the SCSI device of the burner as a number
