Have created a Site Page Template and provisioned an instance into my Team Site's Wiki Library.
<Module Name="CustomInFeature" Path="SitePageTemplates" List="119" Url="SitePages" > <File Path="Page.aspx" Url="Brian_Feature.aspx" Type="GhostableInLibrary" /> </Module>
When I do this, it creates the file successfully whether I am in a Sandboxed or Farm solution. When I am in a Farm Solution, the SPFile.CustomizedPageStatus == Uncustomized. When I deploy via a Sandboxed Solution, the SPFile.CustomizedPageStatus == None.
Does this mean when I provision Site Page Templates in this manner, they are never ghosted, and as a result, always live in the Content Database? If I had lots of Site Collections (think a collaboration portal for a large organization), and each had it's own Site Page Templates deployed as a Sandboxed Solution, couldn't this potentially have a negative impact on the performance of my farm (as each page request, for a page created from this template, would need to pull the page definition from the Content Database, parse, and dynamically compile it)?
Putting this out there, but will try to confirm on my own using SQL Profiler and SQL Management Studio...
