stuff: bz2 support, compress support, many non-required options.
now x_gzip supports "gzip -l" so sysinst should work for these platforms.
gzip will grow slightly - 400 or so bytes on x86 - but this is a small
price to pay for working -l support...
that has holes.
This needs the 'bios sectors per track' before it has been setup - so we
default it to the 'hardware' value. Since both numbers are 63, and this only
affects the size of the headers on extended partitions it should be safe.
leave 4 bytes for the Windows NT Drive Serial Number (DSN) at 440-443
(as mbr_sector.mbr_dsn).
Ensure that all the MBR & PBR code reserves space for mbr_sector.mbr_dsn.
Leave the bootsel magic number at 444-445 as mbr_sector.mbr_bootsel_magic
(instead of mbr_sector.mbr_bootsel.mbrbs_magic), but use 0xb5e1 (MBR_BS_MAGIC)
instead of 0xaa55 (MBR_MAGIC) to indicate that this change has occurred.
Rework MBR_BS_NEWMBR to mean "mbr_bootsel has moved to 400".
Modify fdisk(8) to automatically relocate the mbr_bootsel from 404 to 400
if mbr_bootsel_magic is the old value (0xaa55), and unset MBR_BS_NEWMBR
to flag that new mbr_bootsel code must be used if updating the MBR.
These changes fixes a problem where Windows 2000 or Windows XP would corrupt
the last 3 bytes + NUL of MBR partition 3's bootsel name if the bootsel name
was 5 characters long, replacing bytes 6-9 with the DSN.
Also, by explicitly reserving the space for the DSN we prevent problems in the
future if non bootsel MBR or PBR code had other information at bytes 440-443.
DISTRIBVERDEP in Makefile.distrib, and make both sysinst and
distribution notes use that information so that they rebuild
if the kernel version changes.
Distribution notes didn't have this before, sysinst had a private
(now outdated, since sys/sys/param.h now determines version) copy
of this.
Don't write out dummy extended partitions for unused ares in the extended
partition.
Add some more comments - I write this and I couldn't remember how it worked.
to a 2-clause licence (retaining UCB clauses (1) and (2)), per PR
22409 from Joel Baker, approved by Theo de Raadt, and ratified by
myself - the only discrepancy being the handling of the original
clause 3 in src/usr.sbin/yppoll/yppoll.c.
