Maybe "install" should have an option to make ownership of
installed/generated files match the existing value.

TeX Live could provide a mechanism so that when mktexlsr, etc.
are run by root the ownership is set to that of the pre-existing files
or to some designated tladmin user:group, or at least exit with
warning message if pre-existing files are not owned by root.
