want to save, consider using the BSD shell to create a separate directory in the read-only
/usr partition and moving the files there.
4.2 Updating Files
The Freeway server makes use of read-only partitions and RAM-disk partitions specifi-
cally so the server can be switched off at any time without damage to the disk drive.
Operational files are stored in the read-only partitions and copied to the RAM-disk par-
titions at boot time. The following are tips on updating files on the read-only partitions
of the disk drive.
4.2.1 File Transfers Across the Network
You may use any network file transfer method (fetch, FTP, NFS, rsync, scp, etc.) to
transfer files to the Freeway server, providing that the transfer method is not blocked by
a firewall. The most common way of updating files is to transfer the files to the
/tmp/boot
read-write directory, and using the Freeway menu update method (5-3-3) to copy the
updated files to the non-volatile area as described in Section 4.2.2.
You can always transfer files from anywhere on the Freeway server disk drive to another
system. However, in order to transfer files from another system directly into a read-only
partition on the Freeway server, you must first login to the Freeway BSD shell and tem-
porarily mount the partition as read-write. After transferring the files, remember to
mount the partition back to read-only.
4.2.2 Menu Update Method (5-3-3)
The preferred method of manually updating Freeway operational files is to first update
the files in the read-write operational directory (
/tmp/boot) and then save the changes to
the non-volatile area (
/usr/local/freeway/boot.src). That way if you accidentally overwrite
or delete the wrong file, you can always just reboot the Freeway server and start over.
The most convenient way to save any changes is to go to the Freeway menu and select
menu items 5, 3, and 3 which gets you to the “Build Hard Disk From Boot Server” selec-
