But in other cases if you mount /usr read-only and sure it's same on all servers you can backup single /usr from _any_ server, just like in case with single remote /usr. > If I've got more than 3 or 4 servers to manage in a deployment I typically > use remote-mounted root and /usr filesystems - it makes life an awful lot > easier. If you remote-mount root (using network boot?), /usr and everything else ;-) than that's really can make life much easier, but this setup has nothing with current topic. I'm asking about configuration where you may boot with root but without /usr - that's why /etc/localtime symlink replaced by copy of timezone file, grep compiled without perl regex support, etc. -- WBR, Alex. -- gentoo-server@gentoo.org mailing list
