Comment 3 for bug 562231

purge was probably the wrong word due to its use with apt ... but i merely meant replacing the file unconditionally on an upgrade, instead of merging or whatever, specifically so the compcache settings are reset; i would have to spend a bit of time trying to hibernate with arbitrary compcache values to hope to find some rule of thumb, it depends on available swap and memory size, i think its better to just disable it after an upgrade, or set it to some very small number, like clamp it to 10% so the likelyhood of a hibernation failure would be much smaller.

this could even be a regression, because i could hibernate just fine even with crazy compcache settings before i upgraded to lucid
