ureadahead should have config option to disable or force ssd/hdd mode
Some cheap/old SSDs fail to report their non rotational nature to the kernel. This results in ureadahead treating them as a rotational disk, which can actually cause slower boot times than not using ureadahead at all. There should be a config option to allow affected users to correct this by either forcing ureadahead to ssd mode, or disabling it entirely. Preferably this should be in /etc/default and/or configurable via debconf so a simple dpkg-reconfigure will suffice.

- ureadahead slows down boot on cheap SSDs (e.g. EeePC 900 SSD)
