There is no hash there. You are using a Puppet language feature called a
"selector" to assign a value to variable $acc_sudo based on the value of
variable $mc_servertype. (Which value, by the way, is in each case an
array containing exactly one string. Weird.)

Of course it does. Each element of variable acc_sudo is a string. Your
template says to insert that string into the result, not to interpret it as
another template.

You are making it harder than it needs to be. What you are after can be
accomplished with ordinary variable interpolation:
$acc_sudo = $mc_servertype ? {
'system' => [ "%APP ${fqdn} =/etc/init.d/httpd start,
/etc/init.d/httpd stop,/etc/init.d/httpd restart, /sbin/services httpd
restart" ],
'db' => [ "%DB ${fqdn} =/etc/init.d/oracle start" ],
'app' => [ "%APP ${fqdn} =/etc/init.d/httpd start,
/etc/init.d/httpd stop,/etc/init.d/httpd restart, /sbin/services httpd
restart" ],
}
Note there that (1) the variable interpolation is performed when the string
is initialized, as opposed to when the template is processed, and (2)
variables are interpolated into double-quoted strings only, not into
single-quoted strings.
