I have a btrfs that has utilised posix ACLs / extended attributes and I then subsequently mount that onto a system that does not have the kernel modules compiled for those features? Crash and burn? Or are the extra filesystem features benignly ignored until remounted on the original system with all the kernel modules? Thanks, Martin
