Upgrades of essential packages
Registered by

A not finished implementation to upgrade "essential" packages, i.e those that cannot be removed to make the system work is already in trunk. Currently the code overwrites all files but doesn't take into account obsolete files that might be left by old package versions.
Whiteboard
I'm currently implementing this and I think the following pseudo-code will work:
for all files in old package
for all files in new package
if file exists in old and new
found = true
endfor
if found == false
remove file
endfor
So if file is available in both old and new package list, skip it. If file is only in old
package list, remove it. This must be done for files and links.
