create a zfs vm

[rdunkle34]

I am trying to create a zfs vm:
make update base kernel vm-qcow2,4G,never,efi SETTINGS=26.1 VERSION=26.1.8 DEVICE=ARM64VM ZFS=orange

My build system is using zfs:
zpool list
NAME SIZE ALLOC FREE CKPOINT EXPANDSZ FRAG CAP DEDUP HEALTH ALTROOT
zroot 140G 60.5G 79.0G - - 22% 43% 1.00x ONLINE -

When I run the make command I see the parameter passed:
PRODUCT_ZFS_REQUESTED=orange

I eventually see an error:

Setting up stage in /usr/obj/usr/tools/config/26.1/aarch64
cannot create 'zroot': pool already exists

Is it not possible to create a zfs vm-image on a zfs build system?

Well, it is possible but not with the hardcoded "zroot" name.

Long story short the pool name was adjustable in the past but we had a number of issues with build engineering leading to the current hardcoded default and that one time we had to rename the ZFS pool of a new build host we set up just so we could still provide images with the default "zroot" name.

You can change the name here:

tools/build/common.sh

Lines 75 to 76 in bce80ef

	# XXX can soft-code this later
	export PRODUCT_ZFS=zroot

Cheers,
