after running this command :

[root@ /usr/src/tools/tools/nanobsd]# sh nanobsd.sh
i have these output messages :

/usr/obj/nanobsd.full/_.mnt: write failed, filesystem is full
[root@ /usr/src/tools/tools/nanobsd]#

what does this error say? and how can i solve the problem ?


the other problem is that whether i have lots of WITHOUT options or a few , volume of _.disk.full is about 600MB. what should i do in order to have a very light image? what options should i set ?

thank you all ...
