Again, it wouldn't necessarily matter whether the new packages reached the mirrors (which might well vary between mirrors) since they would be functionally identical with the previous ones. What I want to do is revise the description in the package lists to be displayed in Synaptic. Nor is there any reason I can think of not to record the change in the changelog.
The questions I have are:
Would the package lists be updated with the new info?
Where are package checksums kept?
If the new packages didn't propagate onto the mirrors would that upset the checksums?
If it is technically possible, would Texstar approve?
If not, I think the changes are better left until VB next has to be rebuilt for a different reason, as I'm conscious there's quite enough to be downloaded and installed at present without making more.
