bash warning just after ssh to coreos machine.

[praveenkumar]

Is below warning expected (locale one)?

$ ssh -o "UserKnownHostsFile /dev/null" core@$OPENSHIFT_INSTALL_CLUSTER_NAME-bootstrap.$OPENSHIFT_INSTALL_BASE_DOMAIN

Yeah, it's a bug. Came about when we switched to rpm-ostree compose tree --unified-core. Has something to do with the glibc locales update. Doesn't reproduce with Fedora.

Tagging in for someone to pick up as a card.

This may relate to ostreedev/ostree#1470

It might be something that glibc's build-locale-archive is doing differently in el7?

[miabbott]

On a recent RHCOS system, it looks like the only installed locales are C and POSIX

$ locale -a
locale: Cannot set LC_CTYPE to default locale: No such file or directory
locale: Cannot set LC_MESSAGES to default locale: No such file or directory
locale: Cannot set LC_COLLATE to default locale: No such file or directory
C
POSIX

[ashcrow]

Hopefully we'll be able to fix this in this coming sprint. I've pulled it up in the backlog.
