>Environment:
built on a releng/9.1 machine, but release build happens in a chroot environment, not sure if the build machine environment is important
>Description:
Release build for releng/10.0 fails after running the following...

# mkdir /var/10.0
# cd /usr/src/release
# sh generate-release.sh releng/10.0 /var/10.0


--------------------------------------------------------------
>How-To-Repeat:
# mkdir /var/10.0
# cd /usr/src/release
# sh generate-release.sh releng/10.0 /var/10.0

(same error as above)
>Fix:
Make sure 'unbound' user exists in chroot build environment for 10.0 branches?
