Installing SL would not format and consequently mount the ext4 volumes with the "ordered" mode required to make use of TRIM on a SSD drive by default.
Is there a way to pass a parameter to Anaconda in order to force the use of the ext4 ordered mode during the installation?
As far as I know there's not such an option: if that's true, would it make sense to force a remount of the the ext4 volumes in ordered mode before starting the actual installation of the packages?
My concern here is that in any case the installation will create and delete files while the ordered mode is not used. At the end there will be blocks marked as used on the SSD drive which effectively are not.
If all of the above is not feasible is there a way to cleanly purge the unused block (just after the installation perhaps)?
