IMAP voicemail has moved from building all of Asterisk with a separate
build option (with imap files linked to the main binaries) to a separate
module which can be switched in config. (Only one voicemail module is
allowed at a time, if you have multiple of these installed you can
select between them with noload in modules.conf).
Quirks doesn't handle a flavour moving to unflavoured+subpackage; use
@ask-upgrade so that users of the imap flavour (and only them) are
warned about this at update time.
instructions are meant to work on a fresh install.
- easy cases: replace some '$ sudo somecommand' with '# somecommand'
(while there I've swapped some "${RCDIR}/foo start" with "rcctl foo start").
- replace some 'sudo -u user somecommand foo bar' with
'su -s /bin/sh user "/path/to/somecommand foo bar"' and similar.
Not pretty with the -s, but many of the uids that need to run
these commands have /sbin/nologin as their usual shell.
