Comment 13 for bug 1002500

Or course, as a workaround it's suitable enough (still works, just verified to finish the 5.5 upgrade I just did, easier than editing post-inst as I first suggested).

I can't currently test any 5.1 > 5.5 upgrades, seeing that it's all production, sorry, but if the initscript isn't patched my guess is that the problem occurs there as well (and testing 5.1 > 5.1 isn't possible as there is no 5.1 in the percona repositories anymore as far as I could see)

Thank you for the pointer to 1099428, that is indeed what I am seeing.
