The answer is still to stop thinking about brace expansions and start
thinking about array expansions.
yumargs=( --disablerepo={dag,'$^livnastuff'} )
livnastuff=( dries extras )
yum ${(e)yumargs}
You can keep abstracting this out:
reponames=( dag '$^livnastuff' )
yumargs=( --disablerepo=$^reponames )
livnastuff=( dries extras )
yum ${(e)yumargs}
Or
pkgnames=( kernel '$^livnapkgs' )
reponames=( dag '$^livnarepos' )
yumargs=( --exclude='${(e)^pkgnames}' --disablerepo='${(e)^reponames}' )
livnarepos=( dries extras )
yum ${(e)yumargs}
