My system needs a very high number of inodes on the partition because it is going to store many, many small files. (It's going to be an OSM, OpenStreetMap TileServer running mapnik and tirex).
As far I as learnt the number of inodes of a
ext4 partition can only be created when formatting with mkfs.ext4 (see answer here). Increasing later is not possible but would require one to reformat (see comment here).
So it's really good to do it right at installation. Is there a way to pass arguments to
mkfs.ext4 -T usage-type /dev/something? So I could
mkfs.ext4 -T news /dev/something (usage type
news has a lot of inodes).
