dovecot - Feb 2016 - the prefix number of the configuration filename

Hi all,

I am very curious about the prefix number of the configuration
filename, such as 10-auth.conf
10-director.conf
10-logging.conf
10-mail.conf
10-master.conf
10-ssl.conf
15-lda.conf
15-mailboxes.conf
20-imap.conf
20-lmtp.conf
20-managesieve.conf
20-pop3.conf
90-acl.conf
90-plugin.conf
90-quota.conf
90-sieve.conf
90-sieve-extprograms.conf

What are those meanings of 10,15,20 and 90 ?

Please advise me and thank you in advance.

The configuration files are read and processed according to the sorting
order of their names.  Adding the numeric prefixes allows the order in
which the files are processed to be determined independently of their names.

So, in this case, the config files with names starting with 10 are read
first (i.e., 10-director.conf is processed first).  If the number
prefixes weren't there, then the "acl.conf" file would be
processed
first (instead of near the end).

It matters what order the configuration files are processed in because
later files can override parameters set by earlier files.

At a guess, the directory gets listed, the names get sorted numerically,
and then read in order low-to-high. In theory, the end result will be the
same regardless of what order stuff gets read in, but doing it in a
deterministic order makes troubleshooting easier.

Dear David and Rich,

Thank you for your soon reply. I understood. I thought that would be
special meanings.

Anyway, thank you for your nice reply.
