Thanks for the response but even still, I think it should warrant more
importance than wishlist as this affects the life and performance of the
hardware. The kernel has supported this feature since 2.6.33 and so I
think a little more urgency is required.

Title:
Ubuntu 11.10 does not enter 'discard' filesystem option on ext4
install on SSD drive
Status in “ubiquity” package in Ubuntu:
New
Bug description:
I installed 11.10 the other day on my Macbook Air which has an SSD
drive. Once installed I inspected the ftab and I noticed that it did
not include the 'discard' option on my ext4 filesystem partition. The
discard option enables TRIM support for SSD drives (I realise a lot of
them now have TRIM support in the hardware but for those that don't
but do support TRIM, they need this option) which prolongs their lives
and keeps performance optimal, as it can degrade over time. The SSD
drive should be detected at installation time and then this option
added to the fstab.
