Hi All:

I am trying to get my system to boot from compact flash. I created a disk
image and followed directions I received online in creating the proper
links, etc. but I am having problems when I try to boot the system. Is
there a definitive resource somewhere on the net that explains the steps
necessary to boot off of compact flash?

My configuration is:

512 mb compact flash (will be downgrading this to 128 or 256 mb)
boot off of flash
/ Filesystem on flash needs to be set read only
/var and /tmp are mfs file systems

I have googled for this and have found quite a few resources, but none of
them are definitive or include all of the steps needed to correctly setup
this type of system. Any help would be most appreciated.

TIA,

Jim

/dev must also be a mfs file system, since permissions change when users log in
through a pty. otherwise only a console login will be possible.

tar /dev and /var into archives and untar them within /etc/rc.
remove mount -uw / and rm -f /fastboot from /etc/rc and change / in fstab to ro.

Thats it.
