Re: [PATCH] host.conf(5): order option deprecated, replaced by nsswitch.conf(5)

[Simon Paillard <spaillard-8fiUuRrzOP0dnm+yROfE0A@public.gmane.org>]

Hi,

Do you think this patch can be applied ?

The "order" keyword in /etc/host.conf is not supported anymore for quite
some time.

I cannot find which glibc versions uses order line in host.conf before
nsswitch.conf is used.

Together with the fact this change happened ~7 years ago, here is a patch
*removing* the 'order line', and adding nsswitch.conf(5) in references.
