No worries, couldn't hurt to read up on CDDL[1], *BSD[2] Licences and GNU/GPL[3]. As for your general Filesystem needs, XFS or XFS-LVM is probably the smart way to go. You mentioned something about doing this on USB (solid-state?) storage? You might want to also consider reading up on USB's general policy about write few, read many. In a nutshell, most USB devices don't like to be written to many many times (such as a busy *primary* FS). They have a limited shelf-life of writes )wear leveling) before they go bad (I have an OCZ ATV rubber thumb drive that has suffered this.) This is why they tell you defragmenting SSD's is a *VERY* bad idea, you significantly reduce the write ability of the device.[4][5][6] [1] http://en.wikipedia.org/wiki/Common_Development_and_Distribution_License [2] http://en.wikipedia.org/wiki/BSD_licenses [3] http://en.wikipedia.org/wiki/GNU_General_Public_License [4] http://en.wikipedia.org/wiki/USB_flash_drive#Advantages_and_disadvantages [5] http://www.bress.net/blog/archives/114-How-Long-Does-a-Flash-Drive-Last.html [6] http://www.corsairmemory.com/_faq/FAQ_flash_drive_wear_leveling.pdf -- > A: Yes. > >Q: Are you sure? > >>A: Because it reverses the logical flow of conversation. > >>>Q: Why is top posting frowned upon?
