I agree that it is annoying to have to set it explicitly also in MD_ROOT_SIZE. I believe future versions of the picobsd script should read the picobsd parameters from a single place (probably the "config" file in the directory) and manipulate the kernel config file to insert the appropriate option. > However, after boot completes 'df' says that /dev/md0c has > only 1595 1k blocks. Am I missing something? those are the blocks available for data, after some space has been used for the boot blocks (8KB), label and inodes. If you look at picobsd.bin, you see that the real data (kernel) begins at offset 0xb000 in the file -- i.e. some 36KB are lost in filesystem baggage. Some of this space can be recovered, but i am not sure how. One note-- disklabel 'auto' seems to create blocks of 1k/8k by default, so you might want to add -b 4096 -f 512 options to newfs to make it use smaller blocks in the memory image. Not that this is a problem, but just in case... cheers luigi ----------------------------------+----------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
