This is for the case where you can't decide yet at the beginning how you want to separate the directories under root. What you can do is put them all under one logical volume (/) expanded to your full drive capacity at first. Later, if you decide to, for example, separate out /etc because you are going to do a fresh reinstall, you can just can reduce the size of the initial logical volume (LV) holding /, create a new one to hold /etc, and copy your files over to the new LV without any destructive repartitioning. If you hadn't used LVs, you'd have to copy the contents of /etc off your hard drive first, since you will have to destructive repartioning. If you had put root (/) on a physical partition, and chosen to mount only a few specific top-level directories on LVs, you would lose resizing flexibility for those directories that reside on the physical partition. For example, if /opt was on a physical partition and it grew too big to fit in its original physical partition, you could transfer it to a logical volume elsewhere on the drive, but that would probably mean having too much unused space on the non-resizable physical partition you removed it from. The driving idea here is to stop using physical partitions altogther (including for swap, if you're willing to incur a [hopefully slight] speed penalty), so you have maximum resizing flexibility across your entire storage subsystem. Perhaps in the future, that will be the default mode of operation for Linux OSes (which would give it a leg up over XP in this particular case). -- reply-to: a n d y @ n e o t i t a n s . c o m http://heecheesoft.blogspot.com -- Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Official Website: http://plug.linux.org.ph Searchable Archives: http://marc.free.net.ph .
