Well, I have said also many times also that is not possible to use another option, in the past elive included the selection in the boot (in fact is the first distro who implemented it this way and then other distros did it too) but we don't use this boot system anymore (gfxboot) so it cannot be added on boot time, it is added on desktop start, so the only way to set it is using the boot parameter country=something before the system boots, which BTW I just improved its visibility, should be enough now:
let me try to understand that... what you mean by "no other choices than plain en_us" ? in the language selection english is english, but if you want a specific english (like australian english) this option automatically appears as selection if you boot elive from australia, if it doesn't (because you don't have internet on which is automatically detected) this is for the option "country=au", if you don't see this option because users don't read then you can simply reconfigure your languages at any moment from the configuration, which is what all the users will do when something is not on their choice
that, about the language, but you are mentioning altgr which is not related to the language but to the keyboard step, I just tested it and:
- My system boots in Spanish from Colombia, which is where I'm now (asking me if i want to change the language, in english)
- I select English which includes already some options like from australia or UK
- Then it asks me for the keyboard, preselected is US and if I select the "us" keyboard it will asks me if i want altgr, but just to try to follow your issue I press cancel which will keep this default to "us" and so the default intl-altgr variant
- verifying this, my /etc/default/keyboard is correctly set to intl-altgr
So I need specific details of you altgr issue, it works good here
stills, the choice of the user to add a swap, he should do it following a howto or anything, if he previously didn't included a swap the system is kept this way (remember, is an upgrade mode, not a full installation), it is also not possible to add swap partitions in an already partitioned disk unless you resize on your own risk your existing partitions so this should be made on the user's choice and risk, is not a thing for this type of install and this install is mostly automated in order to simply upgrade your previous system, also upgrading previous elive already asks you this at start "do you want to upgrade your previous elive system?" and it directly starts with the process
The reason why it was included now chrome and not chromium is because chromium had many issues in both virtual box and real hardware in the last months, before that the default was chromium but it was needed to switch to chrome because of that, changing it back to chrome now is not possible since it has not been enough tested for this release and there will be for sure many bugs and surprises, we don't have the time to change it now in the case that chromium is correctly working, this is possible for next versions instead, but again: the live mode is like a demo and don't touch your hard disks, is the user's entire possibility and choice to use chromium instead of chrome or firefox
seems like ssh is correctly working in your installed system by default, in any case i just added in the installer an "unmask mode" before the process which triggered the warning i received
I seen that you added an extra icon on beautyline for it but it doesn't shows as is, in any case not very important, I think it integrates better with beautyline icons the actually used one and can be confusing seeing a double logo of elive, also the icon of elive dont' looks too much integrated with the icon theme but you improved it for this theme which looks better than the original logo 
) at a later stage I get:
we needed the variant configuration and now we don't want it? 
I think other distro's installer doesn't offer these features so they just don't know / let users do things themselves, the elive installer detects, request, suggests, guides, etc
