Re: grub question read-only

The initramfs is mounted read-only I believe, and for the initial mount, your root filesystem is also read-only, remounted read-write later in the boot process. If you use ext3, you'll notice after an unclean shutdown you'll see messages similar to the following: EXT3-fs: recovery required on read-only filesystem. EXT3-fs: write access will be enabled during recovery. -- Andrew J.

I thought, from your question above, that you were ask how to do it in general. the fstab thing will cause it to always mount ro. For one-time use, yours is a fine solution.
