The following is a list of known Mandrake 8 issues for JBuilder 5:

• Review the JBuilder 5 Linux Installation FAQ.
• See article 27291.
• See article 27307.
• Verify that you have at least 250 MB of free space on your /tmp partition. The installer needs this work space and if it does't have it, it may fail silently.
• You may need to hand-mount the cdrom with the following command:

  mount -t iso9660 /dev/cdrom /mnt/cdrom

  To make this change permanent, edit the /etc/fstab file, or use any tool in Mandrake which handles maintaining that file.
