Bug 638316 – sys-libs/glibc-2.26-r3 - nsswitch.conf has no 'files' provider in 'passwd'

• Product: Gentoo Linux
• Status: RESOLVED INVALID

Hi,
  when upgrading glibc on Gentoo::RAP I get the following:

>>> Running pre-merge checks for sys-libs/glibc-2.26-r3
make -j8 -s glibc-test 
make -j8 -s glibc-test 
 * Your /apps/gentoo//etc/nsswitch.conf is out of date.
 * Please make sure you have 'files' entries for
 * 'passwd:', 'group:' and 'shadow:' databases.
 * For more details see:

I think this is a false alarm provided this is Gentto::RAP install.

Adding the 'files' entries help to overcome that but I think it is not worth the effort.

The "compat" provider no longer is available in glibc 2.26, you need to replace it with "files" (and possibly "nis", if you use it) on the lines beginning with "passwd:", "shadow:", and "group:" in $EPREFIX/etc/nsswitch.conf.  Failure to do so will, as the message suggests, cause your Gentoo::RAP install to be unable to look up usernames at all (as there is no libnss_compat.so.2 in glibc 2.26).
