> I see some problems with this approach:
You're right, effectively after doing some test i realize that i was
wrong... simply because newer wpkg update the wpkg.xml file at every
step, not at the end.
I've simply added, in wpkg client pre execution:
if exist "%SystemRoot%\system32\wpkg.xml" (
copy /y %SystemRoot%\system32\wpkg.xml %SystemRoot%\system32\wpkg.old
>nul
)
and now i check '%SystemRoot%\system32\wpkg.old'.
This is not really a ''safe'' method, but can be useful in some case.
EG, i've prepared a recipe to install bacula file daemon client, that i
don't use extensively but only on some client; a second recipe, if
there's a server side .conf file, activate bacula and configure it.
With a check like that, i can add a client (or modify the configuration
file) and have the second recipe do the upgrade.
Because normaly i do that not massively but on that pc, i can check if
works (really, i can do it manually, but using wpkg are very cosy! ;).
If i have some doubt, or i have to propagate some very important
update, i can upgrade revision and have a forced installation.
Rougly: because i copy wpkg.xml to wpkg.old *before* wpkg.js run, if
some configuration file have a modification date newer then wpkg.old,
it is really a new file and have to be ''upgraded''.
It is not true the opposite: but as stated, if really i need to
propagate some config options, i can update the revision.
