  I'm pretty sure we have an eclass function to get the name of the 0

 I can't find one... but found qmail.eclass is using exactly same method.

export GROUP_ROOT=$(id -gn root)

user.eclass provides egetent

  egetent group 0

should give you the same output as $ getent group 0 | cut -d: -f1

id -gn root prints initial group name of the user root. This is
exactly what you want in fcaps.eclass. In linux id accepts only
username as argument, it doesn't support uid.

But if you really want to convert gid=0 to groupname, then use egetent()
as also noted by Cyprien:

inherit user
...
local group=$(egetent group 0)
group=${group%%:*}

Strange. Is this busybox id? /usr/bin/id from both sys-apps/coreutils (Linux)
and sys-freebsd/freebsd-ubin (FreeBSD) just worked fine for me.
