Use libhack and the non-widechar hacked version of curses for
the ramdisk image to save some space.

+= for MAKEFS_FLAGS

branches: 1.20.14; 1.20.18;
Fix PR install/47123 (sysinst fails with "openpty() failed" on many ports):
Add "ipty" to MAKEDEVTARGETS in miniroot/Makefile.inc since "MAKEDEV all"
no longer creates /dev/pty* device nodes and miniroot doesn't mount ptyfs.

branches: 1.19.6; 1.19.8; 1.19.12; 1.19.14;
Remove terminfo.db as it's now embedded in libterminfo.

Use the rescue terminfo.db in our images instead of termcap.

34 different termcap subsets, plus a couple of ports still using
the full termcap distfile. In an attempt to reduce the madness
switch everyone (except the i386 cd install which does its own
thing) to the same (under 8K) termcap subset:

ansi ansi/pc-term compatible with color
dumb|unknown 80-column dumb tty
hp300h HP Catseye console
iris-ansi-ap IRIS ANSI in application-keypad mode
iris-ansi|iris-ansi-net IRIS emulating 40 line ANSI terminal (almost VT100)
sun|sun1|sun2|sun-il Sun Microsystems Inc. console with working insert-line
vt100|vt100-am DEC VT100 (w/advanced video)
vt220-8 DEC VT220 8 bit terminal
vt220|vt200|vt300 DEC VT220 in vt100 emulation mode
wsvt25 NetBSD wscons in 25 line DEC VT220 mode
wsvt25m NetBSD wscons in 25 line DEC VT220 mode with Meta
x68k|x68k-ite NetBSD/x68k ITE
xterm|vs100 xterm terminal emulator (X Window System)

Trying to provide similar functionality across all ports? It'll never
catch on...

Nothing needs disktab anymore, so we'd rather have an inode and
slightly over 1K of space on install media...

Change ramdisks from dhclient to dhcpcd and add corresponding glue to
sysinst. For amd64, the crunchgen binary shrinks by 150KB uncompresssed,
60KB compressed.

branches: 1.14.32; 1.14.42;
Expand the miniroot by 256KB, so that this builds again.

Remove "-Wa,-xgot" hack from DBG flag for broken objcopy-crunchide
that has been fixed by simonb.

BTW, should we also add "-mmemcpy" here to reduce code size?

Rework how SMALLPROG was being used and how INET6 support was enabled.
There's two variables added to Makefile.crunch:

SMALLPROG If 1, add SMALLPROG=1 to CRUNCHENV. [default: 1]
This can be used by various Makefiles to
determine if a `small' version of the program
is required.

SMALLPROG_INET6 If 1 and SMALLPROG == 1, add SMALLPROG_INET6=1
to CRUNCHENV. [default: 0]
This can be used by various Makefiles to
determine if the `small' version has INET6
support enabled.

Only enable SMALLPROG_INET6 for programs on the ramdisks that have INET6 in
the appropriate kernel, and cleanup INET6 setting.
(Note: this means that sysinst won't get INET6 support if the kernel
it's running on doesn't have it).

This change saves a fair bit of space on various install images
(including i386 ramdisk-{ps2,small,tiny}) that didn't have INET6 in
the kernel but were unconditionally getting INET6 support in their tools.

don't bother copying or generating etc/spwd.db, as the miniroot was
switched to libhack a little while ago

branches: 1.10.2;
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.

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

tune inode density of miniroot.fs.

fix IMAGEENDIAN (s/be/le/).

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!
