It does not appear to be that. su - oracle will actually
run /etc/profile.d/oracle.sh
from info:/su
`-'
`-l'
`--login'
Make the shell a login shell. This means the following. Unset all
environment variables except `TERM', `HOME', and `SHELL' (which
are set as described above), and `USER' and `LOGNAME' (which are
set, even for the super-user, as described above), and set `PATH'
to a compiled-in default value. Change to USER's home directory.
Prepend `-' to the shell's name, intended to make it read its
login startup file(s).
from man:/bash
When bash is invoked as an interactive login shell, or as a non-interactive
shell with the --login option, it first reads and executes commands from the
file /etc/profile, if that file exists. After reading that file, it looks for
~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and
executes commands from the first one that exists and is readable.
The --noprofile option may be used when the shell is started to inhibit this
behavior.
And I have added some "echo" debugging lines to some scripts, to verify the
process is working as I expect. This is the output, over a reboot cycle,
with added comments.
