Pretty sure I've tried that. I'll update my travis.yml when I get a chance later and let you know

Dual booting Pie ROMs works but you need oreo or an older version of android as primary.

As far as I know not every pie-based ROM uses treble. The devices that got updates from oreo to pie dont use treble as far as I know.
It might be an option to try DBP on those devices.
Im sadly not able to test this because I dont own a device that runs pie

Did you tried to compile it on your own?

What non-Pie ROMS come to mind to use as primary?

I may just use a relatively small one as primary only so I can use other current Pie roms as data partition roms so I can go back and forth between them.

Update- I tried the above with as oreo primary. I patched then flashed a pie data rom, but it would not really boot up - the primary did even though the ROM section said it was the one flashed.

Chen said getting pie to boot after flashing was the problem, which is still there apparently.

Did DualBoot Patcher ever support early system mount? I figured Pie and Oreo (from late 2018) had that and thus not really bootable as secondaries. I know that's the case with MultiROM as the ROMs flash fine but will crash it when booting. I figure something similar with DBP?

DBP does not support early system mount. If the ROM uses early system mounting even if you do not have a treble device, you would need to modify the boot image to remove the system fstab entries from the device tree (dtb) and add them to the fstab file. And you might need to modify an init.rc file.

@clewis.it, yeah, I figured as much. On my Axon 7 with DBP I had two Oreo ROMs running, boot images pre-patched. That was awhile back though, currently running just Nougat ROMs.
Guess I have some work to do if I want to mess around with more recent Oreo/Pie. Thanks.
