. Some Makefile fixes to automatically differentiate between a normal
compilation and cross-compilation. Also, build compressed images.
. Harmonize ramdisk rc scripts for normal use case and ext2 ramdisk.
. ext2_ramdisk filesystem prototype fixes.
See UPDATING about upgrading clang for dynamic linking.
. allow executables on ramdisk to be dynamically linked; this means
putting a few required shared libraries and ld.elf_so on the ramdisk.
. this makes the ramdisk (usage) smaller when they are dynamic, but
bigger when they're not.
. also we can safely ditch newroot and call mount directly as that is
all newroot does.
. create proto.common to share a bunch of entries between
small/nonsmall cases
Instead of using rootdev= or ramimagedev= in the boot monitor
which are changed to numbers and cannot be used with other
loaders, rootdevname= or ramimagename= are (MINIX-style)
device names always stored as strings.
Patch by Antoine Leca.
. also implement now-possible fsck -p option
. allows unconditional fsck -p invocation at startup,
only checking each filesystem if not marked clean
. mounting unclean is allowed but is forced readonly
. updating the superblock while mounted is now not
allowed by mfs - must be done (e.g. by fsck.mfs)
on an unmounted fs
. clean flag is unset by mfs on mounting, and set by
mfs on clean unmounting (if clean flag was set at
mount time)

. always compile acpi, with clang, so never have
build/clean inconsistencies; can be enabled (i.e. run
at boot time) by setting acpi variable in the boot monitor
. always strip binaries with the right strip cmd, so never
have ack/elf strip inconsistencies
This eliminates a race condition between the disk driver calling
sys_statectl(SYS_STATE_CLEAR_IPC_REFS) as part of driver_announce(),
and the root MFS calling sendrec(DEV_OPEN) on the disk driver.
