+* You installed the sysvinit package. If it's your first installation,

+* 
+* In order to complete the switch, you need to reboot your machine. But
+* beware: just for this time, the usual shutdown commands won't work,
+* because they are designed to work with sysvinit but you are still
+* running s6-linux-init until you reboot. So, for your next reboot (and
+* only this one), the command you will need to run (as root, FROM A

+*
+* Please save your work and perform that reboot as soon as you can.
