I am using Lucid x86_64. I agree 1.8GB is not a lot of space, just meant for apps i installed, 1.8GB is a lot (because i thought (wrongly) /usr contains only user installed apps).

By the way what is DW weekly? > Distrowatch Weekly <http://distrowatch.com/weekly.php?issue=20100524> - An interview with NimbleX as given here *"DW: *Your operating system is based on Slackware. What sort of features does NimbleX offer over plain Slackware? *BR: *I like that Slackware doesn't make strange things with packages as I've seen in some of the other distros and I like that Slackware is meant to be a pure Linux that doesn't bring very specific tools. Thus far it has been a very good starting base for NimbleX which works as live Linux under the hood. The way NimbleX works means that you can't really break it. *Even if you decide to save the changes in a file or in some other way, if you delete the whole /usr directory, at next reboot you'll still have everything there*. If someone chooses to save changes and overwrites important files with something not OK, just deleting the changes will bring back a system that worked exactly as it did when it was installed." Is this behavior specific to Slackware/NimbleX ? > >
