Hello,
 
As a test I try to install Crux on a VMWare.
So I made a 8G disk and formatted it with btrfs.
Then I start up the installer and all the packages installed fine( Core, Xorg and Contrib).
So far no problem.
 
Then I try to change the contents of /etc/rc.conf as described in the manual.
As soon as I try to save it, I get a disk full message.
 
Is 8G to little for a install or is there something else wrong ?
