And indeed, the emerge -e world may in fact be optional. A quite from the current draft of the guide [1]: """ - You may want to run # emerge -e world now. In theory it should not be necessary to do so, but it can not be 100% guaranteed that this is actually the case. ;-) """ I think I'd still like to see people run an emerge -e system regardless...just as an extra safety step to make sure the system packages are sane. But my understanding of what can be affected by a change in CHOST is definitely changed. -Richard [1] http://dev.gentoo.org/~amne/temp/change-chost.txt -- gentoo-user@gentoo.org mailing list
