ext2/3 is mounted async by default, I reckon most linux distros expect some fs
damage to occur because of that over time maybe. Or it's a relic of the days
when that was necessary, maybe it's not really necessary now anymore.

It's just periodic maintenance which is nearly always
set. No more necessary than running a virus check.

UFS/FFS seems to do a better job of not messing up,
although, if you use fat32 as the standard, ext[23] is
nearly faultless as well.
