Comment (by pulkomandy):
package can mounted instantly and can be read on demand (it can't be
done for merged directories because directory list can potentially
consists of many packages so all package contents must be traversed). Only
total package name list should be stored globally that is fast and don't
require a lot of RAM.
But on the other hand you will have a thousand copies of the Haiku package
files in different places. And a hundred copies of all Qt for each Qt app,
each Qt lib, etc).
I don't understand how "read on demand" would work. Maybe for access by
path, but Deskbar will access all your apps to get their icons, so already
all your app packages are mounted when you open the deskbar menu. And if
you do a query in packagefs (for example if you use the "open with" menu),
you need to load everything in the filesystem anyway.
Also it will cause other problems, searching for a file (foo.so) using
Tracker find will return thousands of results in all places where that lib
is used.
Some package models can't be efficiently implemented.
And some can be implemented very efficiently but they just don't work.
Which is worse?
