[REOPENED] Avahi daemon isn't starting on a fresh install

[cedricmc]

NOTE: I am reopening this post since the bug still persists and the workaround does not work.

In November 2013 I did a fresh install on a RPiB. All but avahi and locale-gen seemed to work.
$this->bbcode_second_pass_code('', '# systemctl --state=failed
UNIT LOAD ACTIVE SUB DESCRIPTION
avahi-daemon.service loaded failed failed Avahi mDNS/DNS-SD Stack
avahi-daemon.socket loaded failed failed Avahi mDNS/DNS-SD Stack Activation Socket')
In here, Patatra proposes to change line
$this->bbcode_second_pass_code('', '# grep disallow /etc/avahi/avahi-daemon.conf
#disallow-other-stacks=no')
to (note the 'sharp #' distinctions)
$this->bbcode_second_pass_code('', '# grep disallow /etc/avahi/avahi-daemon.conf
disallow-other-stacks=yes')
This does not work (even after reboot and full system uptdate), so I have reverted the change.
The only thing I could come up with is that
$this->bbcode_second_pass_code('', '# avahi-daemon --debug
Failed to find user 'avahi'.')
however
$this->bbcode_second_pass_code('', '# grep avahi /etc/passwd
avahi:x:84:84:avahi:/:/bin/false')

Does anybody have any idea? Appreciated. Thx.
