<html> <head> <style></style></head> <body class='hmmessage'><div dir='ltr'>hi Len, thank you for the info. The analysis you state is correct and pretty much how I feel about liveUsb vs install on usb as well. You mention that autologic can be disabled from the initrd - or at least that is what the guide states. Well in that case I am confused about were does initrd "jurisdiction" end and where does squashfs jurisdiction begins. Ie where are the limits between the 2, what does one setup and what does the other etc. Is there a guide you can point me to to understand all this? The confusion outflows from the fact that I actually have managed to disable autologin (as explained in the link i provided), but from the extracted squashfs rather than the extracted initrd. Now as far as the username is concerned, the link you provided states in bold that I should remember to create a user and password, but it does not say how. should I create a new entry in <initrd_root>/etc/passwd ? what about a password? should I copy a string from my host's /etc/shadow and create the new file <initrd_root>/etc/shadow and paste the password string in there? or what else?? thank you for your help! <div>> Date: Mon, 2 Feb 2015 21:54:33 -0800 > From: len@ovenwerks.net > To: ubuntu-studio-devel@lists.ubuntu.com > Subject: Re: [ubuntu-studio-devel] how can I alter the username in a live session > > On Mon, 2 Feb 2015, Mike Holstein wrote: > > > > what i did, in a similar case.. i made a close of the OS as i wanted it. when > > restoring the image, i changed the hostnames as i wanted. > > > > it really depends on what you want. if you want a bootable USB stick with > > ubuntustudio on it, that has a "custom" hostname, you can just do a normal > > installation onto that USB stick, and set the name at install.. > > Hey Mike, That does work (I have done it).
