Thanks. And after booting this way can I remove the USB media I booted
from? Or disconnect the server I booted from if it was netbooted?

Hmm I have not tested but I would expect you could. However, if you desire to use persistence with the USB then no.

You may also want to consider the fetch= boot param. From the man of live-initramfs:

           Another form of netboot by downloading a squashfs image from a
           given url, copying to ram and booting it. Due to current
           limitations in busyboxs wget and DNS resolution, an URL can not
           contain a hostname but an IP only.
       Not working: http://example.com/path/to/your_filesystem.squashfs

       Also note that therefore it´s currently not possible to fetch an image
       from a namebased virtualhost of an httpd if it is sharing the ip with
       the main httpd instance.
