Currently sectors of size 512, 1024 & 2048 are supported, the only

that is stored in the hints file. If that search path contained
a non-existent directory (one, say, that had been removed), and
"ldconfig -m /a/perfectly/good/directory" was run, ldconfig returned
an error status without printing an error message. This caused
some confusing bombs when installing ports, in particular.
I changed it so that non-existent directories from the stored search
path are silently ignored. Only non-existent directories named
explicitly on the command line are treated as errors. Also, a
diagnostic is printed if and only if an error status is returned.
In an unrelated fix, ldconfig now silently ignores any directories
named on the command line when the "-r" option is given. Formerly,
these directories incorrectly made their way into the "search
directories" line of the listing. It really should be an error to
specify directories together with "-r", but I don't have time to
fix the manual page in that way right now.

However, he missed the part to compute the kernelsize in kilobytes,
so the minfree consideration was now overcautious. (I've also
changed the return type of dump_size() to void since int was useless.)
Being here, the fact that `vmcore' was written world-readable was just
a plain security hole: everybody who was able to crash a kernel could
later read any confidential information out of it at his will. Create

special handling of 0 as first argument be triggered.
[This bug caused offset 0 to give C/H/S = 0/0/0 instead of 0/0/1.]
The init_sector0 function needs to decrease the first argument
to the second call to dos() by one to be consistent with the
calls to dos() in change_part().
[This bug caused fdisk -i to create bogus partition tables with
the ending C/H/S value 1 too high. This usually gives S = 1
instead of S = maximum, so the geometry guessing in the slice
code and perhaps in SCSI BIOSes was defeated.]
