Doesn't have BSD a TMPFS like Linux has?

If so, it should be possible to have the DHCP logs on the system in
memory without the need of a bigger mfsroot...


For example:
tmpfs                 128M  1.3M  126M   1% /tmp
tmpfs                  10M     0   10M   0% /var/lock
tmpfs                  10M   52k  9.9M   1% /var/run

The size of the ramdisk can not be set because it is file backed. Your
m0n0wall image has a file called mfsroot.gz, which is a filesystem
image. This is mounted as your ramdisk (mfs=memory file system).
Whatever it's size is the size of your ramdisk. The only way to increase
it is make a custom image. The default is meant to be minimalistic. If
you want persistence, you need a real r/w hard disk partition.

512 users is big enough. ISC DHCPD's lease files are text based and
store a lot of metadata, and don't immediately remove old leases.
