I would like to point out 2 small corrections to the debian-live manual http://debian-live.alioth.debian.org/live-manual/stable/manual/html/live-manual.en.html
At this point I am far from able to create and commit changes myself, so I offer them to this list, hoping someone else might propagate them. In section 4.2 the URL given for older, upcoming, and unofficial live images http://debian-live.alioth.debian.org/cdimage/release/ is 404. I would suggest instead listing this URL: https://cdimage.debian.org/cdimage/ In section 4.5.3 the suggestion for adding a partition to extra space at the end of a live image USB stick says to use parted or Gparted. For the current live images, with a xorisso-style partition layout, (for example the file debian-live-9.2.0-amd64-kde+nonfree.iso) parted (as of 3.2-17) and gparted (as of 0.25.0-1+b1) do not detect the first partition, containing the entire .iso, they only notice the small 500KB EFI partition 2, embedded inside it. They see the first partition as empty space, and will allow using the space after partition 2 in creating a new partition 3. Thus these programs are no longer appropriate in this case. Regular old fdisk (as of 2.29.2-1) works correctly for this; gnome-disks (as of 3.22.1-1) works correctly for this. These 2 would be good suggestions for this section of the webpage. I also checked KDE partitionmanager (as of 3.0.0-1) and it does not see the partition 1, and incorrectly offers to include part of it in a new partition, like parted on which it is based I think. Thanks to anyone who can help update this documentation.
