I suppose I have two remarks:

- switching to the cyrus user (with complementary group mail) or any such 
configurable would prove usefull in terms of adoption into different 
distributions, and switching to the cyrus user would perhaps make the wrapper 
a /usr/sbin/ utility (/usr/bin/cyrus of course could be linked to 
consolehelper),

- As the /usr/lib/cyrus/bin/ path is actually a compile time configurable, I 
suppose this wrapper can make use of that fact, and be included into upstream 
in full.

The former notwithstanding, I like what I'm seeing.

I suppose for the switching to the cyrus user, what I always do is, for 
example:

 # su - -s /bin/bash cyrus -c '/usr/lib/cyrus-imapd/ctl_mboxlist -d'

Because the cyrus user does not have a valid shell in RPM based distributions. 
The '-' (for login) is there to make sure we not only *gain* cyrus user 
privileges but also drop the privileges we used to switch to the cyrus user 
(not sure this is damn accurate BTW).

Thank you,

Kind regards,

Jeroen van Meeuwen
