present, this field specifies the media volume that the disc is
contained on. If the volume of a given packages is different than the
current volume of mediaDevice, then the user is prompted --
"This is disc #%d. Package %s is on disc #%d\n"
"Would you like to switch discs now?\n"
If the user selects yes, then DEVICE_SHUTDOWN is called and the user
is then prompted --
"Please remove disc #%d from you drive, and add disc #%d"
This works well for a carefully crafted INDEX file, but more work
needs to be done to sort dependencies on a given package based on the
volume that they reside on, to minimize the amount of disc flipping
required of the user.
This commit is a no-op for normal INDEX files and FreeBSD CDs. These
additional features are only used if the INDEX and cdrom.inf file have
multi-volume support.
to unsigned long long.
Don't be too overzealous with the printing of ks_calls in the total
statistics, cut back from 20 to 13 positions to print (which should last
a couple of years easily (20 digits is enough for 3168 years of calls at a
measly billion (10^9) calls per second.)).

o Implement -c (clear) to clear previously kept headers (note that
dumps not cleared will remain until -c is used),
o Implement -f (force) to allow re-saving a previously saved dump,
o Implement -k (keep) and make clearing the dump header the default,
o Implement -v (verbose) and make most output conditional upon it,
o Emit minimal output for the non-verbose case with the assumption
that savecore is run mostly from within /etc/rc,
o Update usage message to reflect what is and what's not,
o mark -d as obsolete.
Low-level changes:
o Rename devname to device, for devname mirrors a global declaration
and GCC 3.x warns about it,
o Open the dump device R/W for clear and !keep to work,
o Reorder the locals of DoFile according to style(9),
o Remove newlines from strings passed to warn* and err*,
o Use stat(2) to check if a dump has been saved before,
o Truncate existing core and info files to support force,
o First check for the magic and the version before we complain about
parity errors. This prevents emitting parity error messages when
there's no dump,
o Keep track of the number of headers found and the number of headers
saved to support the minimal output,
o Close files we opened in DoFile. Not critical, but cleaner.
- add __unused where appropriate
- PAM_RETURN -> return since OpenPAM already logs the return value.
- make PAM_LOG use openpam_log()
- make PAM_VERBOSE_ERROR use openpam_get_option() and check flags
for PAM_SILENT
- remove dummy functions since OpenPAM handles missing service
functions
- fix various warnings

and acquire the proctree_lock if needed first. Then we lock the process
if necessary and fiddle with it as appropriate. Finally we drop locks and
do any needed copyout's. This greatly simplifies the locking.
