I'll try cpu-/memory-swap-usage this weekend.  But I still wonder why 
there's a problem compiling a kernel with chroot as I can easily compile 
a 6.17.9 kernel from LFS 12.4 in X without using chroot.  And why can I 
compile all LFS 12.4-47 packages until I attempt compiling a kernel with 
chroot?

I should have said I restore the image if necessary.  I create an image 
with fsarchiver and do usually then proceed.  But I'll sometimes resume 
later and may have restored another image in the interim.
