One need to install

• k3b • Xmms• Multires• Xcdroast

However:

Sabah@hep.man.ac.uk

disable the root requirement by editing the files /etc/security/console.apps/xcdroast and

/etc/pam.d/xcdroast

My files look something like this and it works for me on SL302

/etc/security/console.apps/xcdroast

PROGRAM=/usr/sbin/xcdroast

/etc/pam.d/xcdroast

Kickstart via NFS

1. Make a mount point (not strictly necessary):

mkdir /mnt/disk

2. Download the various ISO files for SL. There were four for 3.0.3.

3. Make a directory where you'll place the on-line distribution:

mkdir /SL mkdir /SL/3.0.3

4. Mount each ISO in turn and copy the files from it to the hard drive, as:

mount -o loop SL.303.093004.i386.disc1.iso /mnt/disk cd /mnt/disk tar cvf - . | (cd /SL/3.0.3; tar xvfp -) cd umount /mnt/disk mount -o loop SL.303.093004.i386.disc2.iso /mnt/disk etc.

Sabah@hep.man.ac.uk

5. After the ISO's have been "unpacked" into /SL/3.0.3 (or whatever you choose to call it), export the directory. I.e., add the following line to /etc/exports:

/SL/3.0.3 *.ucdavis.edu(ro)

where you would replace *.ucdavis.edu by your own domain, then type:

exportfs -r

6. At this point you should be able to do NFS installations, assuming, of course, that you have all the NFS "plumbing" already set up. I think that basically amounts to starting the NFS and netfs services.

7. You can initiate the installation in a variety of ways. You may be able to boot from a floppy. See, for instance, /SL/3.0.3/images/bootdisk.img. If you copy that to a floppy via:

dd if=bootdisk.img of=/dev/fd0 bs=1440kyou should get a bootable floppy, that will ask you for the type of installation (local CD, NFS, etc.). I haven't tried this.

We have not done any pxe installation, we hope
