The "objcopy" based crunchide method has a problem on MIPS; it turns global symbols into locals, but relocs are left in place (rather than attempting to resolve-in-place with "ld -r", even with "-Bsymbolic"). Standard MIPS code will generate CALL16 relocs for function calls, but the linker forbids such relocs from being used to call local symbols (such as those turned "local" by objcopy). So, rather than battle the toolchain uphill, work around it for the moment by forcing 32-bit GOT references with the assembler option "-xgot". This will be fixed in a more clean manner in the future.

Make crunched equivalent of pmax root diskimage. Makefile.inc: build `miniroot' [sic] list: list of files to crunch in dot.profile: start up sysinst on boot. diskimage.label.proto: write diskimage label so kernel recomputes label at boot from SCSI geometry..

Commit work-in-progess rototill of distrib/miniroot and associated machine dependent files: - Use infrastructure from distrib/common to build file system images with crunchgen-ed programs from a list file. - Non root ("UNPRIVED") builds from a read-only source tree are possible, as makefs(8) replaces vnconfig(8)/vnd use, devices are generated using common/makedev2spec.awk, etc. - Cross builds should be possible, except that some ports need cross-compile host tool versions of installboot and any appropriate host disk labelling tools. XXX: pmax, sparc and vax need fixing for this! - This code has NOT YET BEEN TESTED on most of the ports. It should work, but it is extremely likely that the file system parameters may need tweaking to get things to fit. See MAKEFS_FLAGS in sparc/miniroot/Makefile.inc for an example. If assistance is required, please ask!

ensure all sysinst-using makefs generated images have at least 15 inodes free, and be consistent how MAKEFS_FLAGS is defined.

- replace image_md_post: target with IMAGE_MD_POST variable, and use that after building ${IMAGE} - use ${IMAGEBUILT} to ensure that IMAGE_MD_POST is only run if IMAGE changes
