bash $PS1 changed with upgrade from 11.1 to 11.3?

[yottabit]

I opened a bug but it was closed, even though I told them what I did to produce the problem. Oh well.

I was running 11.1 and my regular user, added through the Users settings in FreeNAS, had its default shell set to bash. The $PS1 was [\u@\h \w]\$ .

I upgraded from 11.1 to 11.3, and now when the same user logs in, the $PS1 is nas1% , even though I didn't change any user settings. Bash is still being invoked as the default shell, and it's still selected in the Users settings.

If I run bash from the bash login shell, I get the old $PS1 back. But it's not being set anymore for the login shell.

Any ideas why?
