mounting non-install cd in %post cd

[Wehner, Robert]

Using some of the tips mentioned on this list, I've been experimenting
with something like this in the %post section. It doesn't eject the RH
install CD (I don't believe it is mounted once you hit %post). The user
just needs to pull the CD out. Hope this helps.
================
# use pid to get FDs, not "self"
myPid=$$
 
# TTY we'll use for user input
tty_num=8
user_tty=/dev/tty$tty_num
 
# Store original file descriptors
stdin=$(ls -l /proc/$myPid/fd/0 | awk '/^l/ {print $11}')
stdout=$(ls -l /proc/$myPid/fd/1 | awk '/^l/ {print $11}')

# change to new virtual terminal and set FDs there
exec < $user_tty > $user_tty
chvt $tty_num
echo -n "Insert the next CD and then press 'Enter'. "
read ans
echo "Mounting CD..."
updfstab
if (mount /mnt/cdrom); then
   #check that cd is correct; error if not
   disc_label=$(head -1 /mnt/cdrom/.discinfo)
   if [ $disc_label = "uniqueString" ]; then
      # unpack CD contents. 
   else
      echo "This isn't the right CD. Please try again."
    # handle the please try again part
   fi
   cd /
   umount /mnt/cdrom
   eject
else
   # Error out. CD wouldn't mount, try again
   echo "Error out. CD wouldn't mount, try again"
   eject
fi
 
#change back the FDs
exec < $stdin > $stdout
 
echo "Done with CD file transfers"

Subject: mounting non-install cd in %post cd



Been digging around for a while now and can't seem to figure this out.
Is there anyway to eject the install cd in a %post section and then
mount a newly inserted cd? I have tried various methods of using
mount/eject/umount in the %post sections, but can't seem to get it to
work. 

Has anyone had any success doing this? I have multiple CDs with data
that need to be installed after the kickstart rpms are installed
(unfortunately, I can't make the contents of the CDs rpms and I have to
use multiple CDs for this part). I would like to keep from doing the
kickstart, rebooting the system and then prompting for the new cds -
instead would like to reboot only after everything has been installed -
after I have done the kickstart and installed the data from the other
CDs.

Thanks for the help,
