I have ubuntu and archlinux in my computer, the BOOT system (grub) is in ubuntu. When i update grub (grub-update) the ubuntu entry gets the ro-quite-splash line. However the arch entry, after de UUID line, nothing is added automatically (Normally I edit the file grub.cfg and add it manually, which is very annoying). I wish grub did it by himself. Sorry for the bad english ;)

This isn't possible with normal configuration. You have to edit the scripts that are run during grub-update. Take a look at this article. The essentials:

  • Open /etc/grub.d/30_os-prober with root rights for editing.
  • Change the line linux ${LKERNEL} ${LPARAMS} to linux ${LKERNEL} ${LPARAMS} ${GRUB_CMDLINE_LINUX_DEFAULT}
  • run sudo update-grub again

You can also use your own variable for this. For details consider the linked article.
