The rationale was to reduce the overhead for small thumb drives, where maximizing space for data files was considered most important. In practice, most root file systems tend to be larger than 512 megs. For example, the absolute minimum EBS size in Amazon's cloud is 1GiB for General Purpose SSD backed EBS, and 5GiB for HDD backed EBS. Google Compute Engine's minimum Persistent Disk size is 10 GiB. In any case, starting in e2fsprogs 1.46.4 (released August 2021, first shipped in Fedora 36), we changed the default so that 256 byte inodes is used everywhere, including these small file systems. If you didn't like the old default, well, for these really small file systems, the good news is that it's pretty simple to backup, reformat, and restore the file system. (And of course, when the root file system is that small, in general reinstalling it is no big deal.) Cheers, - Ted
