No matter how I write my test promises, I always end up with the error
message "!! Promise constraint conflicts - /var/www/. cannot be
renamed/moved and exist there at the same time".
*** FIRST EXAMPLE *** - does not work:
<snip>
classes:
SRV_APACHE::
"isdir" expression => isdir("/var/www");
files:
SRV_APACHE.isdir::
"/var/www/."
rename => MoveTo("/srv/www/."),
perms => PermsChgrp("www-data"),
create => "true";
"/var/www"
link_from => LinkFrom("/srv/www"),
perms => PermsChgrp("www-data");
</snip>
*** SECOND EXAMPLE (just to make sure...) *** - same error message:
<snip>
classes:
SRV_APACHE::
"isdir" expression => isdir("/var/www");
"islink" expression => islink("/var/www");
files:
SRV_APACHE.isdir::
"/var/www/."
rename => MoveTo("/srv/www/."),
perms => PermsChgrp("www-data"),
create => "true";
SRV_APACHE.!islink::
"/var/www"
link_from => LinkFrom("/srv/www"),
perms => PermsChgrp("www-data");
</snip>
So the race condition is avoided, but cfengine still complains. Ideas
anyone?
Cheers,
Robert
