While we can discuss the merits of doing this for the -STABLE branch, I for one will be quite happy to see this be the case for -CURRENT, where storing three complete sets of kernels and modules (kernel.new, kernel.old, and kernel.dontworryaboutmeiamsafe) consumes vast amounts of disk space with the various debugging symbols, et al. BTW, we keep suggesting people would be foolish to use anything other than MFS/md for /tmp (and maybe other variations on tmp), but our sysinstall doesn't support doing this "automagically". I'm not sure what the right vehicle is for that in sysinstall, but it would be nice to see. Another interesting problem with the current partition layout is the extremely small size of /var, on which we find /var/tmp, which is used for package unpacking before installation. For large packages, such as KDE, LaTeX, and friends, this can be a big problem, as well as for vmware which likes to drop huge paging files into /var/tmp. Combining these various temporary spaces into a single md partition sized to something appropriate might make sense. This is seperate issue from the root partition, of course, but something we might want to look into a strateg for.
