Attempting to boot into ramdisk on 8.3
...o a ramdisk and boot
off of that. I use the following ideas for this:
/boot/loader.conf:
mfsroot_type="mfs_root"
mfsroot_name="/mfsboot"
vfs.root.mountfrom="ufs:md0"
vfs.root.mountfrom.options="rw"
## Tunables
kern.ipc.nmbclusters=32768
net.inet.tcp.tcbhashsize=16384
vm.pmap.pg_ps_enabled=1
accf_http_load="YES"
net.inet.tcp.syncache.hashsize=1024
net.inet.tcp.syncache.bucketlimit=100
The size of mfsboot is 600M.

so people can see what I was doing 7.3ish:
