Hi, I'm planning on setting up an intranet site at home, and I was thinking of putting the web-root onto a removable drive. I'm using Ubuntu 10.04 LTS and I'm planning on installing Apache2, PHP5, phpMyAdmin, and Drupal 7. I also want to be able to access a CVS or SVN repository (which will also reside on the removable drive) from it, using WebDAV.

I'm wondering what effect this would have, moving the web-root to a removable drive? I understand that there are ownership permissions to consider. I'm still quite new to "Linuxland" and I'm not sure of the implications of this idea. In the past, when I used to run Windows, I managed to lock myself out of a hard drive using NTFS permissions and then moving the drive to another Windows OS installation (I gather this has something to do with GUID's being unique to an installation) irrespective of having created accounts with identical credentials. Is the same likely to happen under Linux, such that moving the web-root of my intranet onto a removable drive will only allow it to be used from the machine it was originally installed on?

EDIT: I should explain, I used to run an XAMPP server using PortableApps from a USB thumb drive. I'm thinking of something similar under Linux, having a web server on a removable drive.
