OK, that does make sense. And it can remain entirely generic, without requiring any special bootloader support. /etc would be the exception to this, so I guess you would be happy with that being made into a separate option? This would be a rare choice, so just patching update-grub should be sufficient. Anyone else who wished to avail themselves of it could just edit the kernel command-line. > (As I remember seeing elsewhere in this discussion: you could define > a mount option "mount-in-initramfs" in /etc/fstab that the initramfs > should look for to find out which filesystems it has to fsck && > mount.) This is still a possibility. I discussed an initramfs option for /etc/fstab, but upstream would perfer us to use comment=initramfs or the new free-form x- options e.g. x-initramfs. Like /usr, this could be mounted after the rootfs, with the exception of /etc, as mentioned above. WRT fsck, I think we would continue to mount r/o prior to fsck, as for the rootfs, and then remount r/w afterward in checkroot. Regards, Roger -- .''`.
