These notes are based on:
# poudriere version
poudriere-git-3.4.99.20251127_1
Note the "3GB" vs. the "(~400MB)" in:
QUOTE
First you have to create a jail, which will hold all the building
infrastructure needs.
poudriere jail -c -v 13.1-RELEASE -a amd64 -j 131amd64
A jail will take approximately 3GB of space.
Of course you can use another version of FreeBSD, regardless of what
version you are running. amd64 users can choose i386 arch like in this
example:
poudriere jail -c -v 13.0-RELEASE -a i386 -j 130i386
This command will fetch and install a minimal jail, small (~400MB) so you
can create a lot of them.
END QUOTE
Also, the size looks to be very dependent on the METHOD used
and more:
# poudriere jail -l | sort -k7,7

1725 /usr/local/poudriere/jails/stable15-i386
(Part of that is that METHOD pkgbase includes a /usr/src/sys/
tree, unlike METHOD freebsdci .)
Note: UFS context.
Such sizes seem not so easy to document these days.
