Remote access to /boot filesystem

For 8.4 and later, only the local administrator account (i.e. logging in as ‘admin’) will be able to write files into /boot via SFTP. Supplementary administrators (e.g. TACACS+/RADIUS users with administrative privileges) do not have write access via SFTP.

Oracle recommends you use of /code/images directory as the storage area for system bz images, instead of /boot. This is supported on all platforms as an alternative to /boot, except for systems which are configured in FIPS mode.FIPS requires that the file be written to /boot only. This change is compatible with FIPS operation, as the local admin account is already designated for use by the “FIPS Security Officer”.
