Persistent Home and HD access
Since I started using persistent home, user Knoppix no longer has write/enter acess to the FAT32 hard disk. In the Konquerer file manager, Knoppix only sees a locked tmp directory on the HD. In the console, Knoppix can get ls to list top level directories on the HD, and a "permission denied" error for every file in the FAT root directory.
Root has full access to the HD. Permissions are drwxr--r-- . Attempts to modify permissions with chmod produce a "permission denied" error or are silently ignored.
I'm stymied and looking for suggestions. I'm a total newbie to Linux with only a little Unix experience several years ago, so I might be overlooking something that's very obvious to others.
Thanks for any help!

Re: Persistent Home and HD access
1. First, umount the FAT32 partition.
2. ' chmod ' the mount point to whatever you want
3. Edit ' /etc/fstab ' and make sure you have 'users,rw' in the Options field for that partition/mount point
4. then, ' mount /dev/hda1 /mnt/hda1 ' (subst actual values.)
--Post results, either way....

Persistent Home and HD access
Thanks, Dave! I think I followed your instructions to the letter. Unfortunately....
1. First, umount the FAT32 partition.
The difficulty appears to be in the very first step. With persistent home active, the device is busy. A lazy umount seemed to work, and I was able to complete the other steps. 'chmod' and 'mount' both reported success. But after it was all done, the permissions for hda1 had not changed and user Knoppix still could not access the HD.
I suspect (in my vast ignorance) a solution is going to depend on modifying the persistent home script (knoppix.sh) or creating a preknoppix.sh script. Figuring out where to go next is way beyond me!

Hi Knewbie!
You are right - you have to modify the KPH knoppix.sh a bit. Sorry for that; the update is on the way. Till then you can fix it yourself for the 0.4 version:
Open the knoppix.sh file from KHP and change line #112
from: "mount $p $d 2>&1 > /dev/null"
to: "mount $d 2>&1 > /dev/null"
In other words: simply drop the $p.
I hope this works for you!

--Ok, try this:
After umounting, ' chown knoppix /mnt/hda1 ' and ' chmod a+rx /mnt/hda1 '; follow steps 3 and 4 again. That should at least enable READ access for the knoppix user.

HD access with Persistent Home

Thanks again, Dave, but still no joy. User Knoppix still sees no change in permissions.
I'll be trying the script change suggested by Matthias now, but I wanted to test your suggestion first. Your advice is appreciated!

HD access with Persistent Home...Yes!

to: "mount $d 2>&1 > /dev/null"
That's it! Thank you, Matthias! HD access works fine now.
I'm looking forward to the next update, of course!
I'm thinking of copying the Knoppix directory to the HD, in order to run from the HD without a full installation. Do you know if Persistent Home will work if Knoppix is located on the HD?
Thanks again!

Perfect timing, I was just about to reburn my ISO with the ph scripts included. You saved me from making a coaster.
Is that the only update or are there some more enhancements I should wait for?
Thanx,

There a two fixes for v0.4. The first is described above and fixes issues with fat32 partitions.
The second fixes the problem, that you cannot have your .knoppix file on the same partition as /knoppix/KNOPPIX (i call this a poor man's hd install )
To apply the fix you change the knoppix.sh like this:
Replace the following text in line #148:
"for dir in /mnt/*; do"
with
"for dir in /cdrom /mnt/*; do"
(add /cdrom)
With these fixes you are fully up-to-date. I planned the release of the following version for the next days, but i've delayed it to investigate a possible integration of KPH with Andre Holzhey's interesting project "plugscript". I expect this to take a few days.

I did the edit in w2k using GVIM (vim for windoze). http://www.vim.org
I love this editor. It makes notepad.exe suck bad.
It's even lots better than Note Tab IMHO because it shows the line and charictor position. Sure beats counting while repeatedly hitting the down arrow key.
Anyway post us on any more changes and merges of your kool script.
Thanx again,
