>Description:
NetBSD man chroot(8):
SYNOPSIS
     chroot [-u user] [-g group] [-G group,group,...] newroot [command]
FreeBSD man chroot(8):
SYNOPSIS
     chroot newroot [command]
FreeBSD man rc.subr(8):
${name}_user
   User to run command as, using chroot(8).  if
   ${name}_chroot is set, otherwise uses su(1).  Only
   supported after /usr is mounted.

 ${name}_group
   Group to run the chrooted command as.

 ${name}_groups
   Comma separated list of supplementary groups to run
   the chrooted command with.

So, -u, -g, -G options is not supported in FreeBSD, but used in rc.subr.
I'm checked it in current versions of manuals and problem still exist.

>How-To-Repeat:
grep groups /etc/rc.subr
man chroot
man rc.subr
>Fix:
maybe, we should add NetBSD features to chroot?
