Saxon用于构建rpms。我希望在由libvirt管理的lxc容器中使用它,但是libvirt将lxc配置为阻止mknod(2)
调用,模拟用于构建其chroot。
有办法解决这个问题吗?

看起来这个功能是在最新版本中添加的。
select t.uid, c1, ifnull(c2, '-') c2
from
(select *, @n:=if(@i=uid, @n+1, if(@i:=uid, 1, 1)) n
from tableA
cross join
(select @n:=0, @i:='') param1
order by uid
) t
left join
(select *, @n1:=if(@i1=uid, @n1+1, if(@i1:=uid, 1, 1)) n1
from tableB
cross join
(select @n1:=0, @i1:='') param2
order by uid
) tt
on t.uid=tt.uid and t.n=tt.n
