[Pkg-rust-maintainers] Bug#842634: Bug#842634: rustc: FTBFS (sys_common::net::tests::no_lookup_host_duplicates fails)

[Santiago Vila]

Hi.

This is indeed related to localhost entries as you say, not to the
hostname as I believed.

My localhost lines are like this:

127.0.0.1	localhost
::1     localhost ip6-localhost ip6-loopback

but when I enter the chroot, localhost lines inside the chroot become
like this:

127.0.0.1       localhost
127.0.0.1       localhost ip6-localhost ip6-loopback

This is supposed to be controlled by /etc/schroot/default/nssdatabases,
which reads like this:


# System databases to copy into the chroot from the host system.
#
# <database name>
passwd
shadow
group
gshadow
services
protocols
networks
hosts


Maybe this is just a bug in schroot, for the strange way of "copying"
the /etc/hosts file?

But even in such case: Should we allow packages to FTBFS when the
autobuilder does not have IPv6? It would seems a gratuitous
requirement to me.

Thanks.
