Since v2: - Rebase on riscv port and auxvinfo fix was merged. - Clean up initrd cleanup moves more commands into the new cleanup function from the trap handler comands (suggested by Thomas). - "arch-run: Clean up temporary files properly" patch is now renamed to "arch-run: Fix TRAP handler..." - Fix TRAP handler patch has redone changelog to be more precise about the problem and including recipe to recreate it. - Fix TRAP handler patch reworked slightly to remove the theoretical race rather than just adding a comment about it. - Patch 3 was missing a couple of fixes that leaked into patch 4, those are moved into patch 3. I did look into doing a better job at handling timeouts in places where the migration script can hang (the timeout command only kills the qemu process, but there are other places the bash script itself can still timeout). There are ways it might be possible (along the lines of starting ( sleep N ; kill ) subshell in the backround), but it's very tricky to handle all the details. Existing script has timeout issues already, so this series doesn't add a fundamentally new type of problem here.
