Our current Ubuntu live filesystem builder updates the mlocate database in the squashfs. This is convenient because you get to use locate in the live session without having to wait for updatedb, and because after you install the system it doesn't have to do very much work to update the locate database (particularly true with mlocate versus previous versions of locate). The trade-off is that the database takes a bit of space; it's about half a megabyte compressed here for a 700 megabyte squashfs. However, this should scale with the size of the image, so I think it's reasonably tolerable. Do you think that it would be OK to do this by default (see attached patch), or do you want it to be more configurable? I'd appreciate some guidance on this, as I haven't quite got a feel yet for what you consider to be good practice in live-build. Thanks, -- Colin Watson [[email protected]]
