The prompt display is configured per user, the amandabackup user appears
to not have any configuration.  You can see the same thing by creating a
new user, and wiping out *all* the files and directories in their
homespace, but most specifically, the dot-prefixed bash files
(.bash_profile &/or .bashrc).

My guess might be that the amandabackup user doesn't have a homespace,
or points to one with permissions or SELinux restrictions preventing it
being used as normal homespace.

They're *probably* not, bash is *probably* the default, in the absence
of configuration to the contrary.

I saw a similar thing (shell prompts & disallowed displays) when I did
an experiment of trying to use a FAT32 formatted USB memory stick as the
homespace for a new user.

[tim localhost ~]$ uname -r

Don't send private replies to my address, the mailbox is ignored.  I
read messages from the public lists.
