If I understand correctly, not using tmpfs and TMPDIR makes UML's reads/writes to memory go through the block layer of the host kernel, since UML creates a file the size of your mem=NM parameter, and then unlinks it. Using tmpfs avoids this problem. > Does anyone else run sysemu+skas+exec-shield? Any known issues? I do not use exec-shield, but I would think if it runs at all then your problem isn't with exec-shield. Give tmpfs a try.. -Chris |
