Puppet users - Aug 2011 - Special character in facter variable

Hello,

Im currently trying to get an if condition working.

I have:
if "$mountpoint_path_my-path" {
    file with apache privilege
} else {
    file with root privilege
}

$mountpoint_path_my-path being the facter variable that comes up after
something is mounted.

I had already that kind of thing working but this time, Im trying to
put a path with "-" in it (in my case /var/lib/x-zzz/state).

After some tests, the "-" seems to be a problem: if I have it in my
path, puppet seems to enter the if condition everytime, even when the
directory is not mounted. If I remove it, it works properly and enter
the else condition.

I tried the following syntaxes, without success:
* "$mountpoint_path_my-path"
* ''$mountpoint_path_my-path''
* {$mountpoint_path_my-path}
* "$mountpoint_path_my\-path"

Any clue about a syntax I could use to make this works?

Thanks in advance!

should work on 2.7.2rc2.  Earlier versions
of puppet don''t let you have ''-'' in a variable
name.  Not sure if you are allowed to have
a ''-'' in the fact name, but I doubt it.
Is this your own fact?  How about rewriting
it to not have the ''-''?

It''s a fact generated automatically when something is mounted and
replace "/" with "_" to generate the fact variable.
In my exemple, I have a mountpoint on /var/lib/xxx-yyy/zzz that points
to /dev/drbd0 that will translate automatically to a fact named
mountpoint_var_lib_xxx-yyy_zzz
So the fact includes the "-" since it only translate the path into a
variable name. That part seems to work, it''s calling the fact in my
class that doesn''t seem to be working.

This was changed in 2.7.2rc2, wheer hyphens are accepted.
Can you try that version?

No, I can''t update puppet to a new version because we''re
running
numerous servers with the same configuration.
Isn''t there a way to protect the hyphen, something like a "\"
?

Not that I know of.  Have you considered
getting rid of the hyphen?  Why does your
mount have to be xxx-yyy?  can''t it be xxx_yyy?

Anyway, I''m out of ideas on this.  Good luck.

Yeah, I think you''re right. I''ll change the way my mount
variable is
generated to avoid having a "-" and when possible, upgrade tu 2.7.2

Thanks for the help!
