[CentOS] Yum update changes inode of file

[GKH]

Meikel,

Aside from the stupid way:

create a file "org_name"
copy it to new_name
rm org_name
mv new_name org_name

I don't know of a way to change inode
and keep md5 the same.

Does anyone know of a way?

This would be the perfect question for this forum.
