[Bug nss/22349] New: [RFE] user specific hosts entries

            Bug ID: 22349
           Summary: [RFE] user specific hosts entries
           Product: glibc
           Version: unspecified
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: nss
          Assignee: unassigned at sourceware dot org
          Reporter: riehecky at fnal dot gov
  Target Milestone: ---

Is it possible to add a new NSS that reads something like ~/.hosts for user
specific host aliases?

Ideally, this would permit users to add their own local resolution for
specified hosts, while preventing this from leaking into other user's

Use Case:
- a web developer wants to override the resolution of a hostname to test a
specific node in a round robin cluster.
- an IOT developer has a pile of devices with IPs that may change depending on
test conditions.

- preventing services like NSCD from caching resolution of user specific
results is mandatory so that no one poisons the hosts.db
