mnt-system "Knoppix" shortcut respawns

[hhhorb]

Hi, I'm running 6.4.4/LXDE on a persistent USB and am curious why I can't delete the "Knoppix" desktop shortcut. It respawns on reboot, even if I delete it as root.

Thanks.

Without any information given we don't if you have set up your "persistent USB" correctly. Might be you just have a poor-man flash install on USB without a persistent store. You can check using these few commands 'df', 'cat /proc/mounts', 'fdisk -l' etc. There should be a /KNOPPIX-DATA directory if you have a persistent store.

@kl522, thanks for responding:^)

With Knoppix 6.4.4, making a persistent USB is absurdly simple... transfer the ISO to a USB using Unetbootin, boot from the drive and you will be asked if you wish to add persistency on first boot, and the prompt lists a minimal storage amount (200MB) and max available (280MB on my 1G USB). If you skip this step you will get prompted on each subsequent boot. Even with a measly 280MB of memory for user files, I was able to configure Compiz settings, get Flash working (create the folder "plugins" in ~/.mozilla and dump the plugin file there), save and set a desktop wallpaper, install an icon set, a GTK theme and numlockx, customize Iceweasel including installing Adblock Plus, and customize Lxpanel, all of which are restored perfectly on reboot. Really an amazing distro.

So yeah, persistency works, except for this desktop symlink named "Knoppix" reappearing. In the symlink's "Properties" it says the target is /mnt-system, if I click it it takes me to /home/knoppix/Desktop/KNOPPIX, the file structure inside is the same for both paths. KNOPPIX-DATA exists and here is the output of "df"...

Obviously this "problem" is a triviality as it only takes a moment to delete the shortcut, I was just curious about Knoppix's boot process and file structure.

Thanks again for your response(s).

Since your persistency is working except for this desktop symlink, it is likely it is re-created each time. True enough if you look at /etc/X11/Xsession.d/45knoppix, the symbolic link is recreated each time X is started.

@kl522, DING DING DING DING DING!!!

In /etc/X11/Xsession.d/45knoppix there are lines #199 & #200...

# Create a link to our KNOPPIX DVD 
[ -r /mnt-system/KNOPPIX ] && ln -snf /mnt-system "$HOME"/Desktop/KNOPPIX || rm -f "$HOME"/Desktop/KNOPPIX

Commenting out line #200 prevented the symlink from being created. Many thanks! :^)
