Extending this Linux packages example. What if some proprietary device driver called X? This driver is not from Linux source package, but every update of Linux will cause the need of rebuilding X's deb packages. Sources are independent but deb packages of X depends on Linux's deb packages. If you change RNG's probability distribution from uniform to normal, then probability distribution will stay normal, but parameters will change (e.g. average). You can compare this two m-files: uniform.m:
figure(1) hist(rand(1,100000),100,1) for i = 2:10 figure(i) hist(max(rand(i,100000)),100,1) endfor normal.m: figure(1) hist(randn(1,100000),100,1) for i = 2:10 figure(i) hist(max(randn(i,100000)),100,1) endfor If you combine normal distribution with seeding RNG with (source package name, update version, client-machine-id), then this will keep number of random variables to low values and combined probability distribution will be closer to normal. In this scenario Linux's packages probability distribution will be normal (because it is independent) and X's will be like for i = 2 from 'normal.m' file. You can calculate parameters of probability distributions for dependent groups of deb packages (coming from the same source packages) using lists of installed packages from users that report bugs. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1214482 Title: Not-grouping dependent packages in Phased Updates changes propability distribution for entire group of dependent packages.
