Unfortunately, I don't think there is any way around it.

At the very start of the process, prior to the actual start of the task 
sequence the client receives its "orders" so to speak.  This includes all the 
required packages, versions, etc.  When the time comes to use a package the 
client refers back to this original inventory to verify that what it is pulling 
from the DPs is valid.

When a package is updated while a TS is running, when it comes time to access 
that package what the client finds on the DP no longer matches what SCCM told 
it to expect.  So, in the client's view the content it keeps trying to access 
is corrupt (the hash mismatch).

We had to do a number of things to get around this.  One, we leapfrog packages. 
 Once a package is in the TS it is never touched again.  If we need to make a 
revision we create a new package, update it and once it is out on the DPs we 
swap it into the TS.  There was one package in particular that we could not do 
this with (its content was automatically updated as part of a backend process). 
 In that case we had to set aside a downtime window where no builds could be 
performed.

Subject: [MDT-OSD] TS gathering package version

I run into trouble occasionally when I update a package that may be part of a 
task sequence.  It seems that the TS collects the version number of the package 
at the beginning of the TS and then if the package is updated while the TS is 
running, it fails from a hash mismatch.  The TS running on the client is 
looking for an older package (and hash).

I wonder when the package version is collected, and is there any command I can 
run to make the package number be recomputed during the TS.
For instance, if I have a TS line that says Install Notepad, there is no 
package number listed in the TS - it just says install this package.  At what 
point is the package ID/version captured?   Can I get around this problem?  I 
hesitate to update packages because in a place like mine, there is always 
someone running a deployment and there is no good time to update packages.  Are 
there steps I can take to help mitigate this problem?

The package might be called explicitly in the Task Sequence or it might be 
called by dynamic packages reference ie -- Package001=XXX00001a, 
Package002=xxx000067, etc.  When does the version get captured for xxx00001a?  
Why not just in time?

What do you do about this?
