-Subject: [PATCH] mount tmpfs-as-rootfs (initramfs) with -o
- nr_blocks=0,nr_inodes=0
-
-I would have preferred to write this patch to be able to pass
-rootflags=nr_blocks=0,nr_inodes=0 on the kernel command line,
-and then hand these rootflags over to the initramfs (tmpfs)
-mount in the same way the kernel hands them over to the block
-device rootfs mount. But at least the Debian/m68k initrd also
-parses $rootflags from the environment and adds it to the call
-to the user-space mount for the eventual root device, which
-would make the kernel command line rootflags option be used in
-both places (tmpfs and e.g. ext4) which is guaranteed to error
-out in at least one of them.
-
-This change is intended to aid people in a setup where the
-initrd is the final root filesystem, i.e. not mounted over.
-This is especially useful in automated tests running on qemu
-for boards with constrained memory (e.g. 64 MiB on sh4).
-
-Considering that the initramfs is normally emptied out then
-overmounted, this change is probably safe for setups where
-initramfs just hosts early userspace, too, since the tmpfs
-backing it is not accessible any more later on, AFAICT.
