It's 32- or 64-bits depending on what you tell it to be.
Mine's i686 - would you mind confirming that if I
flick this over to x86_64
this will really prevent my stretch/i686 VPS booting, as the wiki indicates?
Yes, if you select a 64-bit bootloader it will not be able to boot a
32-bit kernel.
I'm a bit surprised by this, as it means my only
option is a full reinstall
which scares me (redoing all the configs).
As the article indicates there are multiple options, of which
reinstallation is one. Why is it that you find this your only
option?
I would have thought that the simplest option for you would be the
one where you install a 64-bit kernel, since that would most likely
involve no reconfiguration of anything, except for the few steps
necessary to install the kernel itself.
Also, I must ask, if it would be very difficult to re-do all the
configs, does this mean that you do not have backups of the configs?
Assuming you do have backups of the configs of everything,
application configuration don't tend to change very much between 32-
and 64-bit installs. But maybe identifying what to install and going
through setting its configuration is what you're talking about
there. The "migration VPS" option gives you two weeks to do it.
Again as the article out points out, you do have probably a couple
of years to keep going with 32-bit guests, and even then we will
find a way to keep booting them. It would just be prudent to find a
way to switch before then.
Note that everyone currently running Ubuntu has a much more pressing
deadline: 18.04 LTS was the last Ubuntu release that will support
32-bit. There aren't any more upgrades for Ubuntu on 32-bit. By the
time it comes around to 20.04 there will only be a 64-bit option
when installing or upgrading to that.
CentOS already made that choice, and yet more will follow. Debian
will be slower but I'd give it 5 years to abandon i686.
Cheers,
Andy
