Unless you're sharing some drive space between each installation (such as a common swap partition, or things like sharing the user data directories between each OS), then one OS doesn't do anything to the other operating systems. I've done that sort of thing before - having totally independent multiple installs in one PC, and having shared data directories between them. You shouldn't need to unplug a drive to make a fresh install clean from any other installs, however it does make easier to avoid accidentally selecting the wrong drive to install to. But, on the other hand, if you're changing what drives are plugged in, or playing with BIOS options for which one to boot up, the system may identify each drive differently (e.g. what was considered the first and second drives might be numbered differently). > Will a thompson gateway TG782T ADSL modem/router be sufficient to act > as a basic server modem for the above proposal. Never seen one, but just Googling the name produced several links about problems with them. Over the years, I've gone through about three ADSL modem/routers, two of them Billion's, and another that I can't recall. All were much of a muchness, worked well enough until random technical failures occurred, as any electronic device may suffer from. Some routers overheat, badly, because the casing is a bad design, air-flow wise, but you can circumvent that by sticking a fan next to them. I'm inclined to believe that my problems stem from how most domestic ethernet ports are not floating transformer coupled on the data lines. So any ground loops between the equipment can stress them. It gets worse when you interconnect equipment across different rooms or buildings, especially when equipment uses ungrounded switchmode power supplies. Expensive routers/switchers use galvanically isolated ethernet ports that avoid that problem (there's a signal transformer between inputs and outputs, with only a magnetic coupling between each side of the transformer, and they're rated to handle significant undesired interferring signal voltages without dying). -- [tim@localhost ~]$ uname -rsvp Linux 3.9.10-100.fc17.x86_64 #1 SMP Sun Jul 14 01:31:27 UTC 2013 x86_64 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
