random from within the range at file read time. Very useful if you
want to avoid having a fleet of machines melt a server by all trying to
contact it at a precise time every morning. See docs for details.

XXX apb suggests, quite reasonably, that ?10-16/2 should mean
something like 10,12,14,16 or 11,13,15. I'm too lazy to do it right
now, but it should be done.
XXX vixie suggests, quite reasonably, that if you're using "?" one
should delay randomly by 0-59 seconds. In the modern NTP world, you
could imagine that with a million well synchronized machines the
second just at the minute would be hit quite hard. I'm too lazy to do
it right now, but it should be done.
XXX cron needs to be updated to Vixie's cron 4.1 code.
As the input is read from a specfile into a tree of linked lists,
keep each linked list sorted. The sort order is the same as that
already used by "mtree -c": directories sort after non-directories, but
otherwise names are sorted in the order used by strcmp().
RT_ prefix and use them appropriately, instead of making copies. Make
pppd use the RT_ROUNDUP macro; fixes proxyarp setting on 64 bit hosts.
XXX: All this should be pulled up to 5.0
so that it can return 128KB, 256KB and 512KB properly instead of
truncated 0MB or rounded 1MB.
Problem reported by nisimura@ on port-amd64 and port-i386.
ddb.onpanic to 1, change it back to 0 in sysctl.conf and make sure
postinstall installs this setting.
This avoids us trying to dump while booting from install CD, but keeps
the default the same once we are far enough through /etc/rc.d. Failing
earlier is unlikely to be recovered by an automatic reboot.
OK: core.
ddb running on crash dumps, but with two notable changes:
- Breakpoints, watches, etc are obviously never going to work so they
are not handled.
- You can pipe output to the shell, e.g. ps | grep foo
Items remaining to be done:
- Port it to architectures other than i386. This isn't difficult, just
a case of making db_disasm.c/db_trace.c or their equivalent compile
and work.
- Make more of the "show" commands work, e.g "show uvmexp".
NetBSD conventional bswap16, bswap32, and bswap64 functions or macros.
In a non-tools build, include <sys/types.h> and <machine/bswap.h> to
get definitions of these functions. In a tools build, rely on the
functions or macros being provided by nbtool_config.h, but don't incluce
<machine/bswap.h> (which might not exist in a cross build).
This should address a problem building on OpenBSD, which has swap16,
swap32, and swap64 macros that conflicted with the local definitions.
The problem was reported by Alexander Bluhm, but this patch is quite
different from the one he suggested.
return something other than just 0.
caveat: statvfs is done for the mountpoint path, so might not give
the truth about a directory inside the mountpoint.
