Assuming you mean grub.cfg, you shouldn't do that. Your initialisation system will take care of switching from ro to rw at the correct time. > I tried to find what's broke, but failed. > > I can't find who remounts root filesystem into rw mode. Is this some > systemd generators magic? Or is this happens inside initrd? You need to look at your logs. I've only had root switch to ro upon getting i/o errors, which is what the fstab entry for root specifies: LABEL=swan07 / ext4 errors=remount-ro 0 1 It's a safety feature to stop those errors from gradually corrupting the filesystem further.
