Yann you might need to provide some more info. What does 
"jail is not happy" mean?

At a very high level, you should be able to:

- upgrade host to 15 (currently in ALPHA5 only)
- continue to use your existing poudriere setup
- add a 15.0 builder by `poudriere jail -c -j 15amd64 -v 15.0-ALPHA5 -K GENERIC` or similar

FreeBSD releng infrastructure typically runs a recent-ish CURRENT 
now at 16.x, and builds from sources, using the makefile targets
in /usr/src/ & /usr/src/release to ensure a pristine build env,
not poudriere.

Generally, I'd suggest waiting for at least the BETA or RC to
test, follow https://www.freebsd.org/releases/15.0R/schedule/
for timelines.
