Just attempting to get some help for a problem I've noticed in Knoppix 5.3.1 when using the persistent disc image feature on a USB Flash drive.
I've noticed that folks posting problems in the Ubuntu forums tend to get at least a discussion going, and often problems do get solved. Posting to the Knoppix forum, as I have for several peculiarities I've noticed, goes somewhere into thin air. About the same response results when I post to the Debian forums, although often if someone in the club like, say, a mod like Tina (lavene) posts the same problem I noticed then everyone flocks to help solve it and the answer appears. Leaves my saying, "huh?" My post remains unanswered as if I don't exist. Weird.
Anyway, once a persistent image (knoppix.img) is created and the system is rebooted with Knoppix applying that image, then either logging out and in or restarting from then on, all the cd/dvd drives will appear as icons on the desktop at bootup and none of them are accessible any longer except by K3b or by mounting them with KDE's Kwikdisk. That nice Knoppix icon that holds the running Knoppix DVD is gone, replaced by one labeled simply "DVD," and additional icons are placed on the desktop for that drive (/dev/hdc), /dev/hdd, and an additional one for /dev/cdwriter and one for /dev/cdrom. All of the drive icons are useless except for the ones still there that weren't adversely effected, my 2 hard drives and the Sandisk Cruiser Micro USB Flash drive. Those behave normally and I can mount/unmount them and change read/write mode on them fine.
The cd drive icons are useless. Inserting a cd into the empty tray (/dev/hdd) does not make a new icon appear and if I try to right click and mount the existing icon I get a "This feature needs Hal" message.
If I open KDE's KwikDisk and click on the drive using that, the cd mounts in /mount/hdd and can be accessed by browsing to /mount/hdd and opening it there. Trying to open /mount/cdrom, which should open it, brings up that "This feature needs hal" thing.
So there is no way to access the running Knoppix DVD from anywhere even though the system is running from it, the KDE autorun stuff doesn't work, and I must use KwikDisk to mount, access or unmount cd or dvd inserted into my empty drive. Strangely, the browser accesses the home html file on the dvd just fine. Just nothing in /media will open it.
The /etc/fstab is exactly the same as the Knoppix version that is there without the persistent image being used.
I attempted to upgrade all the hal and dbus stuff thinking there may have been some fixes in the newer Debian Lenny versions, but doing that corrupts the hal package so it is no longer installable. I've since deleted that knoppix.img and now have an empty Flash drive to start over with. But since this has happened twice I am sure I'll get the same result.
/dev/cdrom /media/cdrom auto user,noauto,exec,ro 0 0
/dev/hdd /media/hdd auto users,noauto,exec,ro 0 0
/dev/hdc /media/hdc auto users,noauto,exec,ro 0 0
Before, and the first boot into the persistent image, those are not on the desktop except for the Knoppix DVD and inserting a disk into /dev/hdd results in an icon being created and it can be used to access the inserted media.
After the boot or logout/in following the first use of the persistent image, icons appear for all those drives on the desktop but no Knoppix icon for the DVD, a DVD icon appears instead that is not usable. And only K3b or Kwikdisk can make use of the hdd drive. No way for normal mounting as that stupid "this feature needs hal" message appears.
Any help with this? Do you think it's a bug or is this behavior normal when running with a persistent knoppix image?
