Public bug reported:
I assume that you decided for uniform distribution in the random number
generator. If group of dependent packages is installed only when all
phased-update-percentage values (for each package) are smaller than the
present percentage on server - it will change probability distribution
for the whole group of packages.
Just run this:
figure(1)
hist(rand(1,100000))
for i = 2:10
figure(i)
hist(max(rand(i,100000)))
endfor
in octave and look at histograms for i>1 (i is the number of dependent
packages).
