Is it possible to create a portable User Account in Ubuntu? What do I mean by portable? Well, lets say I have a usb drive. On the usb drive I have a typical home folder (unencrypted) with all the config stuff and personal file, pic, music, etc. I plug it in and it mounts. Is it possible to get the dm to see this? I'm making the assumption this user account was created with the Live distro avoiding any potential compatibility issues.
Yes, just use persistence.
Make a file in the root directory of any partition or your flash drive (after making a live flash drive from the iso)
Make a file system on the file
Remove the reserved blocks
Then when you boot the USB (or CD) , use the persistence option (you have to manually edit the boot line)
You can use this method with USB or CD.
See - Ubuntu Wiki Persistence for details
You can loop mount the file with any distro
Adjust the mount point as needed (/home , /home/User_name/data , up to you).
When it is loop mounted you can access the data.
