dsl 0437903aaf The 'padded by' number displayed for multi-floppy images has been out by 8k
per floppy for a while.  (The rest of the sums are ok).
Change the 'padded' size to include all the space in the last 8k block
of the tar file.
Similarly if the image doesn't fit, report the exact amount of overflow.

dsl 0132bc8a19 Report the exact number of free bytes in the install floppy images. 2005-09-04 19:29:31 +00:00
dsl 1ac6a7dc0f Tell pax to use 8k (not 10k) buffers when generating the tar archive
of 'boot' and 'netbsd'.
This makes it possible for the tar archive to end at the end of the 2.88M
floppy, instead of either 4k before, or 6k after.
Gives us a whole extra 4k.
The very observant might realise that we don't need the final 1024 bytes
of nulls written to the floppy either, so they could be deleted!

dsl 306d28231b When a boot floppy overran, the reported excess size was 8k too big. 2005-03-04 16:01:58 +00:00
dsl 3d7f966def The code to pad floppies could sometimes overwrite the end of the kernel
(causing the decompress to generate random data).
I've changed it to pad using:
	dd if=xx.fs of=xx.fs conv=sync conv=notrunc bs=${floppysize}b count=1
which isn't subject to rounding errors!
This might be the fix for PR/25552

lukem ed9fb819aa When calculating the number of disks, take into account that every
floppy needs an 8KB tar volume header, not just the first.
Fixes size calculation bug reported by Frank van der Linden.

lukem d9aa9519e8 Invoke ${PAX} with '-O' so that various errors don't hang the make
or the command with an interactive question.  (This also prevents
weird problems if a directory element of '-f path' is missing and
'make -j N' is being used).

lukem 897d27df90 - add support for [-s suffix] to buildfloppies.sh (defaults to "",
rather than the previous ".fs").
- add support for (optional) FLOPPYSUFFIX in Makefile.tarfloppy, and
  use appropriately
- remove (now unnecessary) custom release targets in alpha/instkernel/*

tv 73a896df92 Exit with nonzero status if the -i (installboot) command fails. (The media
certainly won't be usable in this case.)

lukem 2db638e823 buildfloppies.sh -- build floppy images from the given files.
It can write multiple disks (up to a maximum number), and optionally
install a bootstrap or pad the last disk to the image size.
