Huh? My OpenSolaris box (snv_121) doesn't have an /etc/bash. And
according to the man page, it runs /etc/profile:
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, ...
[Experimenting backs this up - bash logins display /etc/motd.]
ATFM, it will execute ~/.profile iff neither of ~/.bash_profile and
~/.bash_login exists.

The problem is that 1) the number of shells is potentially unlimited
(zsh was installed by default on my system, sources /etc/profile, but
because they forgot to add it to the list of shells that use
/etc/profile, doesn't get /etc/motd.), and 2) most shells read more
than one file, with results that depend on how the shell was invoked
and the contents of the files that were previously loaded.
I suspect you got bit earlier because bash processed /etc/bash/bashrc
*after* ~/.profile, thus overwriting your setting from .profile. With
zsh, you can disable that by unsetting GLOBAL_RCS in ~/.profile.

It would have to have at least three dimensions: OS, OS release, and
shell (releases with more than one version of a shell can treat them
as different shells).
