Stefan Hegnauer's Homepage - How to update poudriere STABLE

as there seems to be no documentation for this ...

a)    Using snapshots

In Poudrière:

• create a new jail getting the current snapshot of STABLE, and using the current date in the name to distinguish it from other jails:

  poudriere jail -c -j 12stable_amd64_20190823 -v 12.0-STABLE

• delete the existing old jail:

  poudriere jail -d -j 12amd64

• rename the newly created jail to the old name:

  poudriere jail -r 12amd64 -j 12stable_amd64_20190823

• Warnings can mostly be ignored ...

Outside Poudrière:

• delete old jail to regain space:

  zfs destroy tank/poudriere/jails/12stable_amd64_<old_jail>

b)    Using the host environment (preferred)

One-time setup:

• Make the host’s /usr/src and /usr/obj/usr available within the poudriere jail using nullfs (remove the soft link to /basejail/usr/src)
• Copy the hosts’s /etc/src.conf to the poudriere jail
• Create the poudriere jail using the existing host infrastructure:

  poudriere jail -c -j 12amd64 -m src=/usr/src

Update after a host update:

  poudriere jail -u -j 12amd64
