I have a pure initramfs working in the deskjet patch, but not with
busybox. It loads the initramfs directly from the romfs build directory,
not from a mounted image. Had to patch up the vendor makefiles to
make real dev nodes and such.
End result is you have to be careful to delete all of ./romfs/* whenever
you really want to get something to go away, and run make twice because
the romfs build happens after the kernel has already snarfed up what is
in there. A more elegant way of doing this would be nice.
It sounds like you have further problems somehow, but this worked for me.
My makefile "romfs" target is like this -- the important stuff is the
loop over DEVICES.
romfs:
[ -d $(ROMFSDIR)/$$i ] || mkdir -p $(ROMFSDIR)
for i in $(ROMFS_DIRS); do \
[ -d $(ROMFSDIR)/$$i ] || mkdir -p $(ROMFSDIR)/$$i; \
done
# explode these now... we need real nodes for ramfs
for i in $(DEVICES); do \
DEVN=`echo $$i | sed -e 's/,.*//' -e 's,.*/,,'`; \
MIN=`echo $$i | sed -e 's/.*,//'`; \
DEVT=`echo $$i | sed -e 's:[^/,]*,:: ' -e 's/,.*//'`; \
MAJ=`echo $$i | sed -e 's:[^/,]*,:: ' -e 's:[^/,]*,:: ' -e 's/,.*//'`; \
rm $(ROMFSDIR)/dev/$$DEVN ;\
mknod $(ROMFSDIR)/dev/$$DEVN $$DEVT $$MAJ $$MIN; \
done
# these permissions are needed for openpty and family to work
# on non-ptmx ptys
chmod 620 $(ROMFSDIR)/dev/[pt]ty[pqrsPQRS][0-9a-f]
for i in $(FLASH_DEVICES); do \
touch $(ROMFSDIR)/dev/flash/@$$i; \
done
dirs=$(DIRS) ; \
for i in $$dirs; do make -C $$i romfs || exit $? ; done
$(ROMFSINST) -s /var/tmp /tmp
$(ROMFSINST) ../../Generic/romfs /
$(ROMFSINST) ./inittab.vendor /etc/inittab
$(ROMFSINST) ./rc.vendor /etc/rc
$(ROMFSINST) ./passwd.vendor /etc/passwd
$(ROMFSINST) ./group.vendor /etc/group
if [ $(CONFIG_BLK_DEV_INITRD) = "y" ]; then \
ln -sf bin/init $(ROMFSDIR)/linuxrc; \
fi
echo "$(VERSIONSTR) -- " `date` > $(ROMFSDIR)/etc/version
