Installation attempt, slinky-0.5.02 [Was Re: [RULE] slinky-0.5.02 for Fedora Core 4 FC4]

[C David Rigby]

Hello Franz, et. al.,

I have had a bit more time to work with Franz's new intaller, so here is 
a little more feedback. This references our exchange on 5 August 2005, 
but I have snipped all except the relevant portions.

I reworked my modules floppy. So as to mimic the directory structure of 
the full slinky-0.5.02-modules.img, I created various subdirectories and 
copied files from the image to the floppy. Some of this may be 
unnecessary, but it all fit, and it works, so I was conservative. The 
directory structure of the floppy now looks like this:

/lost+found/
/2.6.11.12/kernel /drivers/pcmcia/rsrc_nonstatic.ko
/2.6.11.12/kernel /drivers/pcmcia/yenta_socket.ko
/2.6.11.12/kernel /drivers/scsi/sd_mod.ko
/2.6.11.12/kernel /drivers/scsi/sr_mod.ko
/2.6.11.12/kernel /drivers/scsi/sg.ko  (this module is not really needed 
for this install)
/2.6.11.12/kernel /drivers/scsi/pcmcia/aha152x_cs.ko
/2.6.11.12/kernel /drivers/scsi/pcmcia/qlogic_cs.ko (I have one of these 
also, but not yet tried)
/2.6.11.12/modules.* (all files of this type - maybe I do not need them?)

Now, the following commands serve to load the needed drivers to access 
the external SCSI CD-ROM drive:

insmod rsrc_nonstatic.ko
insmod yenta_socket.ko
insmod aha152x_cs.ko
insmod sd_mod.ko
insmod sr_mod.ko

Followed by these commands:

cardmgr       (activates PCMCIA-subsystem & probes for CD-ROM drive, 
links it to /dev/scd0)
ln -s /dev/scd0 /dev/cdrom (link so that the installer can find the CD)

For repeated installs on this machine, I can simply dump all of that 
into a script. For future developement, possibly a more sophisticated 
"connect_2_pcmcia_cdrom" might be able to probe multiple modules, etc. 
Just a thought...

The script was still stuck in a loop here, so I editted the script 
further. Here is the relevant bit of code, which is at the very end of 
the file /scripts/select_method.sh in the rootfs.gz image inside 
slinky--0.5.02-disk1.img:

...
    I will try to use <$CDROM_DEV> as your cd drive.
    You will have the opportunity to change this
    later in the install, if need be.
" 12 70
    done

    echo CDROM_DEV=$CDROM_DEV >> $install_log
    have_device=1
    ;;

The addition of the line "have_device=1" didn't quite get it, but I 
finally realized that the "done" above, which is the end of the 
preceeding "while" loop, needed to be below the setting of the flag 
variable. So, I changed it, and this worked to proceed with the 
installation:

...
    I will try to use <$CDROM_DEV> as your cd drive.
    You will have the opportunity to change this
    later in the install, if need be.
" 12 70
#    done

    echo CDROM_DEV=$CDROM_DEV >> $install_log
    have_device=1
    done
    ;;

I'll update my installation report with these modifications once I get a 
little further.

Ciao
