Make editor configurable (variable EDITOR, also usable by disklabel(8)).
Move disklabel(8) calls into `md_prep_label()'.
Eliminate two uses of `sed'.
Eliminate `awk' in upgrade.sh.
names. As before the first program name (field 3) is the one "with source".
The remaining entries specify just filesystem links.
Additional keywords processed by makeconf.awk:
ARGVLINK: used to specify additional link directives for crunchgen(1); no
filesystem links appear for these.
SRCDIRS: crunchgen `srcdirs' directive
CRUNCHSPECIAL: crunchgen `special' directive
Note:
- `list' was more-or-less arbitrarily split into MD & MI parts.
- the `crunch' configuration file is generated from `list's
with the `makeconf' awk-script.
- Makefile assumes there's a `../<arch>/miniroot' directory with
MI configuration files.
