From 045fa1e1142552799ad3203e9e0bc22a11e866ea Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Mon, 22 Oct 2012 06:43:51 +0000 Subject: fs: add filesystem switch libary, implement ls and fsload commands Implement "ls" and "fsload" commands that act like {fat,ext2}{ls,load}, and transparently handle either file-system. This scheme could easily be extended to other filesystem types; I only didn't do it for zfs because I don't have any filesystems of that type to test with. Replace the implementation of {fat,ext[24]}{ls,load} with this new code too.
