WARNING: Limitations
Although you have full access to the files and applications of the installed sys-
tem, there are some limitations. The kernel that is running is the one that was
booted with the rescue system. It only supports essential hardware and it is
not possible to add kernel modules from the installed system unless the kernel
versions are exactly the same (which is unlikely). So you cannot access a sound
card, for example. It is also not possible to start a graphical user interface.
Also note that you leave the "change root" environment when you switch the
console with Alt + F1 to Alt + F6 .
