Re: boot linux rw/ro and /tmpfs

I think this is more about how a system is fsck-ed.
From what I got in this post, if the kernel parameter is set to ro, init will do fsck. However, since by default mkinitcpio/initramfs included the fsck hook, setting the kernel parameter to ro will make it redundant because essentially you're running fsck twice. Of course, this depends on your setup.
It's safe for sure because you're double-checked your filesystem, but it is redundant.
