    Thank you Sudodus,

    I want to make a USB thumb drive with live boot capability, persistence and data storage/transfer between computers in as simple a way as possible. Can you briefly tell me what to do in mkusb?

    I want to do this so that I can sign onto public wifi with my laptop in as secure a way as possible, but also use the thumb drive for standard storage and transfer of files, perhaps to a library PC as well. I may also want to use a VPN, the "Firejail" sandboxing application and a service like OpenDNS for interacting with the internet when on public wifi.
    I have two thumb drives, and 8GB and a 16 GB, but could buy larger ones, e.g., 32GB. Is there a preferred size?

    But it is very important that you allow the system to reboot and shutdown completely, give it time to flush the buffers in other words write the data to the 'casper-rw' partition completely. If you unplug the USB pendrive too early, the system will be damaged.
    OK, I will be careful. In a straight live boot without persistence, nothing can be written to the thumb drive, so I assume there is some increased risk of errant code, viruses, malware being written to the thumb drive when it is set up for persistence. Is this correct?

    OK thanks for the instruction. I will only update manually a few apps, like Firefox and Libre Office and infrequently. I can see now that it is the kernel that is unchanged on the thumb drive, even if it is set up for persistence. Only the data in a partition for persistence can be changed. (And, of course, data in a partition that is set up for regular data storage and transfer, e.g in both Linux and Windows) can be also changed.)

    Thanks again,

    While it maybe convenient for a poster to have just one thread for topics that could very well deserve a new thread of their own, the topics in the thread that aren't reflected in the thread's title may be missed by others who feel that the thread's title doesn't reflect their interest.

    For this reason, I suggest that each topic, even if somewhat related, has its own thread and that each thread be given a nice descriptive title

    I wrote the mkusb quick start manual for this purpose, see particularly the pages 23-25.

    You find the "full description" at the following links,

    help.ubuntu.com/community/mkusb

    help.ubuntu.com/community/mkusb/persistent

    Please ask specific questions, if you need more help.

    As you have already agreed with @vasa, it is better to discuss these items in a separate thread.

    Yes
