I usualy have a number of swap partitions since the max size of a swap
partition is kind of limited. I was thinking of changing it to do swapon
twice. The first time early in the boot would skip mounting any swap
areas that had kernel core dumps. Then after the savecore it could do
swapon again

Hmm
For a one TB FS with 8KB block size you need 2^(40-13) bits
to keep track of b

Yes, if you have a huge FS.
The problem is that the checking of the CG bitmaps during an fsck
require that you have all the bitmaps in core, and then linearly
traverse the entire directory structure to identify which bi

I question the wizdom of what you're describing. If swap space needs to
be made available for fsck to run, then what happens to the crashdump

Recently(?), a change was made so you can no longer open a swap partition
read/write after it is activated with swapon(8). In the current boot
sequence, swap is mo

I agree, but t

Heh, well, stuff happens. I think your idea of opening swap exclusive is
probably a good one, but it will require some gymnastics to accomodate
it. One thing that'd really help is an option
