Unknown service smtp/tcp on 64 bit chroot

• Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] [ attachment ]

postfix-2.2.5-5 on OpenSuSE 10.0 for Linux x86_64. Using chroot for
the smtp services fails with 'unknown service smtp/tcp'.

The chroot environment was set up by examples/chroot-setup/LINUX2 but
that script only copies the 32 bit libraries. For x86_64, the chroot
environment also needs the /lib64 versions of nss etc. Patch below
fixes it for x86_64. Postfix 2.2.7 has exactly the same version of the
script.
