It uses ad0s1 and ad0s2 for code and ad0s3 for /cfg, as usual, 1GB total. Other space of SSD is dedicated to ad0s4 where I have ad0s4b (8GB) for crashdump and the rest as ad0s4a for /var/crash. And ad0s4b is NOT configured as swap. There are 4GB of RAM and no swap here. More than 3GB of RAM are generally free. Eugene Grosbeinhome | help
