Your traffic costs 100$/gig, but you aren't affecting your traffic by mounting the ISOs as loopback. All you are affecting is the usage of disk drives, by saving 650 odd MB per ISO because you don't need have duplicate files. When you have to do this repeatedly (say for 4-5 OSes you may mirror, times say 2 images per OS) however many times the OSes are releasing new versions it adds up to a fair chunk of time, even if you are practiced at it, and it only takes a few minutes for each new release. In contrast, simply buying a new HD, while this may have a higher initial cost, does not need to be re-bought all of the time because as new releases are released older versions are moved to archive sections (generally, FreeBSD seems to have an unusually high number of old releases in the main directory, if I must say so myself, up to ~50G now, aren't we? ;) > i suspect loopback stuff will be used a lot more once DVD-R images start to > be released.. to date, i only know of SuSE Linux offering this. i was Perhaps so, it would certainly make it more sensible in my opinion, as I'd be saving more HD space. However, I don't know how popular DVD images will be in the near future, even on cable|DSL ISOs still take quite a while to download, larger images would make this even slower. As well the number of DVD-Rs in public use is rather low I imagine. And please, don't CC: me ;) I promise, I am on the list. -b To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hubs" in the body of the message
