@LoveEachDay: What is the correct value for --data-dir?

In the master branch it is --data-dir /etc/milvus/etcd-data.
But when I apt-get install milvus==2.0.2-1 the content of /etc/systemd/system/milvus-etcd.service is different: --data-dir /var/lib/milvus/etcd-data.

/var/lib/milvus/etcd-data/ exists and holds files, /etc/milvus/etcd-data does not exist.

[LoveEachDay]

We change the default data directory for milvus 2.0.2.
/cc @Bennu-Li

[LoveEachDay]

For ubuntu the default data directory for etcd is /var/lib/milvus/ectd-data, and for centos related the default directory for etcd is /etc/milvus/etcd-data .

And for now we don't put the service config for ubuntu into milvus repo.

[schuberttobias]

I think I've applied all changes as requested and explained by your CI.

Do you have a branch name convention? I did not find one and emulated @xiaofan-luan 's style
