Misleading error message when case-insensitive file/dir names from config files clash with case-sensitive file system.

[Info Akra]

Hi,

Is it noted somewhere that Dovecot (v 2.0.9) doesn’t use case in directory names in its config-files?
I found that out the hard way (i.e. a week of debugging)!!

in /etc/dovecot/conf.d/10-master.conf, the line:
  unix_listener /var/spool/postOut/auth/dovecot-auth {
creates a:
Jul 29 22:15:58 server dovecot: master: Error: service(auth): unlink(/var/run/dovecot/) failed: Is a directory

but
  unix_listener /var/spool/postout/auth/dovecot-auth {
works just fine (with matching case changes on the directory names themselves).

That’s on running on Ubuntu 12.04.4 TLS, standard installation from apt-get, in cooperation with Postfix 2.0.9.
