I'm not a big fan of prefixes for executables: we already have
file namespace separation thanks to directories. Not precisely
knowing _where_ to put them is not an excuse. /usr/libexec/cyrus-imapd
seems fine to me. Most executables are neither general purpose
(/usr/bin) nor for sysops (/usr/sbin) as they are required to run
as the 'cyrus' (or whatever) user. Adding /use/libexec/cyrus-imapd
to $PATH for the cyrus user only sounds sane enough. If a command
can be sensibly used by any user, it belongs to the system bin
directory, but the prefix in the name is natural in this case:
cyradm comes to mind, it's so natural that it already has it. B-)

That's close to impossible to solve for developers. It has to be
dealt at package creation time (sed/perl). It's more a deficiency
in the old glorious UNIX man system than anything else.
But recent man executables have provisions to handle this nicely btw,
just few distros fully make use of them. man on fedora has MANPATH
and MANPATH_MAP. MANPATH_MAP fits the separate directory approach well.
Just install manpages in /usr/share/cyrus-imapd/man or something.
Just my 2c.
