Vanilla V7 didn't come with RL02 support, so all I can give you are the parameters used for the RL02 images I have here with V7: rl tm root rl 0 swap rl 0 swplo 18000 nswap 2480 In other words, the filesystem should be no bigger than 18,000 blocks. The mkfs manual says: If the prototype file cannot be opened and its name con- sists of a string of digits, mkfs builds a file system with a single empty directory on it. The size of the file system is the value of proto interpreted as a decimal num- ber. The number of i-nodes is calculated as a function of the filsystem size. The boot program is left uninitial- ized. Distribution V7 had roughly 2,600 files & directories. If I had to set a value, I'd choose 5,000 or so.

You'd have to disassemble the kernel. Alternatively, consult the size of the free block list on the disk's image.
