A proposal to periodically run the fstrim
command on Fedora 32 systems was discussed recently on the Fedora
devel mailing list.
fstrim is used to cause a filesystem to inform the underlying
storage of unused blocks, which can help SSDs and other types of block
devices perform better.
There were a number of questions and concerns raised,
including whether to change the behavior of earlier versions of the
distribution when they get upgraded and if the kernel should be responsible
for handling the whole problem.
