As Alan explained, there might be a point where you need to run a= =20 32bit app. Maybe some legacy game (Civilization Call To Power comes to mind) or some n= ew- but-the-vendor-sucks software. Without multilib you can either choose not to use that software (which isn'= t a=20 choice if you really need it) or you can reinstall everything. And all that for a couple of megabytes on a tens, maybe hundreds of gigabyt= es=20 harddisk. du -h /usr/lib32 362M /usr/lib32 but: rootfs 57G 23G 34G 41% / yeah, shocking. Almost a 114th of the harddisk used for multilib stuff ;)
