But of course it's right: the resulting archive can be better picked up from a directory like /tmp, it should just have enough space available (allthough a compressed ports tree should be less than 500 MB). > and it might as well be compressed, something like: > > # cd /usr > # tar cf - ports | gzip > /var/tmp/ports.tgz That is possible - if space is an issue (and not time); it is also possible to do like this: # cd /usr # tar cjf /tmp/ports.tar.bz2 ports I think it will even be better compression ratio using the BZip2 algorithm (tar option j instead of z). One thing worth mentioning: The ports tree should be "clean" before transfering (which is not a problem if it has just been fetched). If you have already worked with it, make sure to have been running # make clean in the ports main directory, or simply delete all work/ subdirs that might contain tons of files not needed. The directories ports/distfiles/ and ports/packages should also be checked. As they contain compressed stuff, compressing them won't be much helpful. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
