That's an easy and significant benefit. So, why not do this on all boxes, even those that have / and /usr under separate filesystems? Granted, localtime will be unreadable whenever /usr is not mounted, but is that really a problem? Typically it will only be an issue at boot-time and in single user mode. The current time and file system times will be displayed in UTC, but this is only a small temporary inconvenience for the operator. Cron might not do its work as expected, but it is unlikely to be running in circumstances where /usr is not mounted. Perhaps some log files might be affected, but if /usr isn't mounted, then /var probably isn't either. Have I missed some big potential problem that might outweigh the benefit of using the symlink even when /etc/localtime and /usr/share/zoneinfo are on separate filesystems? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
