But am I sure? as I understand it (very limited understanding here), the chroot knows nothing about the rest of the system, but has access to the hardware etc. So in the chroot environment you would have access to the sarge network. This procedure is detailed in the debian docs [1]. You probably WON'T get the replacing a running kernel in the chroot, but if you do, you can safely ignore it, IMO. > > Just how much is it possible to do in a chroot? everything, except mess with the system the chroot is running within, unless you give it permission to. Lots of stuff gets run in chroots for security reasons -- web servers, mail servers, user's shell accounts etc. Its a decent way to segregate tasks while protecting the main system. note my disclaimer above. > > Is it, for example, possible to do an entire Debian install in a > chroot? yes [1]. > so that existing users of the system don't have to care while you > install a complete new system in another partition? > :) [1]. enjoy A [1] http://www.debian.org/releases/stable/i386/apcs04.html.en
