Comment 1 Ondrej Vasik 2011-01-03 11:51:58 UTC

Well - I tend to say this is NOTABUG - as /etc/host.conf is still in use in glibc (recently we added multi on option to default /etc/host.conf to allow localhost alias even on IPv6 machine). Anyway - man page documenting host.conf file is coming from man-pages package and glibc resolve/res_hconf.c still uses /etc/host.conf - so I think https://bugzilla.redhat.com/show_bug.cgi?id=144687 is no longer correct.

Feel free to explain why it should be considered deprecated - and discuss this with glibc maintainer - Andreas Schwab - first. Closing NOTABUG - file still in use (and res_hconf.c uses it by default - with no use of nsswitch.conf).

Comment 2 Siddhesh Poyarekar 2011-04-21 07:15:19 UTC

host.conf is in fact used by glibc is not completely obsolete. But there is no reason for it to be installed by default with the line:

order bind,hosts

since the order keyword is precisely the one that does not do anything anymore. Keeping this intact in a default installation gives the wrong impression that the line is in use.

At the minimum, we could remove this 'order' line and install a blank file in case removal of the file creates confusion about the file not being in use at all.

Can we reopen this bz?
