For normal usage, they are in tmpfs along with portage but I mount them over nfs for larger packages as memory is too constrained (just comment out the lines in fstab) - most packages take much less than a hundred mb or so for the storage unless its glibc or the like. After a reboot they are using no space (of course) and it just takes a sync to replace portage and I use http-replicator on the network so distfiles are not a problem. Lightning fast for smaller packages, but yes, much slower over nfs. That being said, its still faster (over nfs) for some packages than my old athlon desktop. However, swap over nbd is sloooowwwwwww, but works :) BillK
