How else would you > upgrade? A normal upgrade does 'installworld' followed by some sort of /etc updating tool. It doesn't do 'make distribute'. Also, this is related to why one is not guaranteed to be able to do an 'installworld' unless you've booted into the new kernel first (though it often works, and 'make distribute' also often works, but often != always). The thing is, there is no notion of cross-tools, etc. for things like installworld and distribution. We have always expected the host to have ITOOLS that work. Note that this exact situation has happened before back when cap_mkdb and pwd_mkdb grew endianness flags for release cross-builds. The pwd_mkdb flag and the change to enable it in etc/Makefile were both made on the same day. (The cap_mkdb change was made earlier, but that appears to be more a result of the testing cycle for cross-building releases than an intentional delay.) -- John Baldwin
