[$] Fedora and fstrim

A proposal to periodically run the fstrimcommand on Fedora 32 systems was discussed recently on the Fedoradevel mailing list.fstrim is used to cause a filesystem to inform the underlyingstorage of unused blocks, which can help SSDs and other types of blockdevices perform better.There were a number of questions and concerns raised,including whether to change the behavior of earlier versions of thedistribution when they get upgraded and if the kernel should be responsiblefor handling the whole problem.
