The changes to use NLS for strerror sometimes cause one of my virtual machines to deadlock. This virtual machine runs 9-CURRENT, acquires its IP address via DHCP (virtualbox host-only networking), has no default route and has /usr/local and /usr/home NFS mounted. When the DHCP lease expires such as by resetting the date after a VM save&restore, one of the route(8) commands executed by dhclient-script(8) fails and calls strerror(3). Following the default NLSPATH, catopen(3) looks in /usr/share/nls first; because the catalog is not there it then tries in /usr/local/share/nls which deadlocks because the network is not available. I currently use the attached patch which returns failure on any attempt to open a catalog for language "C", but I think this is not correct. Am I using a configuration that is not supposed to work (NFS mounted /usr/local with DHCP in particular), or should this be fixed in some other way? -- Jilles Tjoelker
