After seeing this PortableUbuntu software on LifeHacker
I downloaded it and am a happy user since.
However, I am moving to a new hard drive which has 12 times the capacity of my old one...and I decided to partition the new drive into 5 pieces. Partition C is dedicated to contain 'Windows' and 'swapfile', partition D is for all 'Program Files', partition E is for data like 'Documents and Settings' etc.
PortableUbuntu sees only the first partition (C:\) and the Ubuntu forums tell me that I have to edit the 'portable_ubuntu.conf' file first and 'fstab' file second. Editing the conf file was not a problem, the fstab file is. Since this file is stored in an image file, PortableUbuntu has to run and locks it. Now I thought to use 'su' and 'sudo' to upscale my rights to root level to see if I had any possibility to override/disable/sneak past the lock.
There seems to be no root level or I am already on it. PortableUbuntu has only one user defined (pubuntu) and it is not possible to add one (using the GUI at least). When I open a console the text before the cursor shows which user is logged on and that is (by default) pubuntu. The forums tell me that this pubuntu is a user with root privileges.
My question is, how do I change the fstab file?
