[01:39] <beantaxi> catred: Thank you for your response. Perhaps I was using 'user data' too loosely ... I was referring to anything you would use in the creation of a VM, at creation time, including MIME-encoded data, eg created with `cloud-init devel make-mime` etc. 
[01:46] <beantaxi> minimal: Thank you for your OVH- and IONOS-specific details. In the case of IONOS, I don't see any way of setting user data other than their DCD tool, which doesn't look like a tool I'd enjoy using. In the case of OVH, it would just mean doing some homework, but looks possible.
[13:17] <minimal> beantaxi: the IONOS document I linked to shows how to use their API via curl to set user-data
[15:56] <beantaxi> minimal: Thank you, and sorry I missed mentioning that before. I did see that, but was deterred by the big long curl, and their mentioning that it only is valid on Volume creation -- which, from reading their API documents, is not true, it's actually on Server creation, hence the /servers path ... or maybe I'm just misunderstanding them.
[16:01] <beantaxi> minimal: I'm still interested in how to use cloud-init to 1. add a per-boot script to a running instance, such that it executes on reboot, and 2. remove that script, or ideally flag it for removal after one execution. If that isn't supported in the cloud-init CLI, I'd be interested in how to make it happen with scp etc
[16:29] <minimal> you have the script itself disable itself at the end of its (first) run?
[17:07] <Davidian1024> hey group, i've been unsuccessful at finding out how to do this via the docs so far.  so i'm giving in and asking here.
[17:08] <Davidian1024> i'm trying to get cloud-init to add the i386 architecture to an ubuntu instance on first boot
[17:09] <Davidian1024> basically, the cloud-init equivalent of this command: sudo dpkg --add-architecture i386
[18:12] <beantaxi> Davidian1024: This might be a very silly question, but can you put it in runcmd: in a cloud config?
[18:15] <Davidian1024> i was imagining there would be some apt or dpkg options that did this.  but, yeah, using runcmd to run a little script is looking like my only option.
[18:21] <beantaxi> Davidian1024: I just grepped the source and checked the docs ... the only references I see to dpkg are related to grub. E.g. https://cloudinit.readthedocs.io/en/latest/reference/modules.html#grub-dpkg. I don't know if that's helpful or not.
[19:22] <minimal> beantaxi: cc_apt_configure handles .deb related repo configuration
[21:48] <beantaxi> Davidian1024: To quote minimal above, cc_apt_configure handles .deb related repo configuration
