[arch-general] fstab and root filesystem

Hello, I have been playing with the initramfs, and I noticed that the root filesystem is mounted in read-write mode in early init. Since, by the time /etc/fstab is available, the filesystem on which it resides (presumably, the root filesystem) is already mounted, and mounting it is anyway early init's task, not real init's (because the real init cannot be found without the initramfs), there seems to be no point in keeping it listed. I haven't found anything about this, but commenting out the pertinent line hasn't broken anything. Is it fine, or are there any reasons for it to be listed in fstab? Regards, Kalrish
