[11:23] <xnox> realtime-neil:  i don't know where you are getting preseed/late_command from. I don't think anything in ubiquity uses that at all.
[11:23] <xnox> there is oem-config/late_command, but that's for oem-config only, not ubiquity.
[15:58] <realtime-neil> xnox: is there really nothing that shells out (and is checked) after the installation proper and before the machine reboots?
[16:34] <xnox> ubiquity/success_command
[16:34] <xnox> but not checked.
[16:34] <xnox> but like you can make it hang, or crash things.
[16:34] <xnox> what do you expect it to do?
[16:34] <xnox> realtime-neil:  you can ship a ubiquity plugin, if you want custom ux.
[16:37] <realtime-neil> xnox: i was expecting something like a `preseed/late_command`; i.e., it if fails, then then error is propagated to something the user can see
[16:38] <realtime-neil> Is there something easier than a ubiquity plugin?
