One of the reasons I have remained with 32 bit operating systems for so long is that I make daily use of a chroot environment to update 3 out of my 4 distros. This saves an awful lot of time and good deal of wear on tear on my hard drive by reducing the number of reboots I have to carry out. This technique is something that I do not want to give up on. The trouble is that whilst it is very easy to chroot from a 64bit distro into a 32 bit one, it is next to impossible the other way around, and that is what I would need to do because LMDE - my main distro - is 32 bit and likely to remain so for the forseeable future.
I have googled this of course, and I have found several explanations as to how people have achieved this seeming impossibility, but they are so horrendously complicated they make my brain hurt. Most of the explanations I have seen seem to revolve around trying to get gui programs like Firefox or Wine running through chroot and this may be why they are so difficult to follow. I don't want to do any of that, all I want to run is 2 commands "apt-get update" and "apt-get dist-upgrade".
So the question is, as my needs are so simple, is there a simple way to achieve them? Or do I go on using 32 bit until my computer breaks and it is time to buy a new one?
