            Bug ID: 30683
           Summary: Add environment override for /etc/resolv.conf path
           Product: glibc
           Version: 2.38
            Status: NEW
          Severity: normal
          Priority: P2
         Component: network
          Assignee: unassigned at sourceware dot org
          Reporter: carlos at redhat dot com
  Target Milestone: ---

We support RESOLV_HOST_CONF to override /etc/hosts.conf, so it makes sense to
extend this to override /etc/resolv.conf.

Possible options include a RESOLV_CONF environment variable.

Example:
RESOLV_CONF=/tmp/resolv.conf getent ahosts example.org

Should this be a tunable that has an environment variable specified?
e.g. GLIBC_TUNABLES=glibc.resolv.conf=/tmp/resolv.conf

It would have to be SXID_ERASE (default) IMO since AT_SECURE should not alter
their resolver configurations and subprocesses should also consistently produce
the same resolution results as the parent process.
