Any pointers to where you created yours > from? Michael Ellerman gave it to me. It is very simple. Its /init is just $ cat init #!/bin/sh # devtmpfs does not get automounted for initramfs /bin/mount -t devtmpfs devtmpfs /dev exec 0/dev/console exec 2>/dev/console exec /sbin/init $* and /sbin/init is a link to /bin/busybox It is all run by an expect script that just waits for the login: prompt, logs in a root and runs "halt". All the debugfs messages appear before the kernel finished booting. --=20 Cheers, Stephen Rothwell --Sig_/P/pgJNsB/CxxTA7Im0mlgh5 Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAl0gdTkACgkQAVBC80lX 0GxtMwgAg65k4ek0yHkqfCBG5PI9RuZtSI0V6Uej7ZTeOsREdXsphNAqdrNdsaaQ f1I7g1Myw+HhY/j/NiWC6BNvdc78y3XqkiwhvwWnW5EHto+Fx9qtWEnIY2JB0xEn myCBt9EpYCMYVaoMxOZ1RHKUAJ5uavJRoQAHCltiarvJIYrvAIE0vuUqk4Xbd1GK tB9WZOQLbC3pvYlW+SFu/RtQmepWDNgv3iq4YJpU2MiYfAXvX1Fotqc3uSWCHaX6 jRTtCiMFedZvnR1DYyEa1Zk5nh3bY5E5ZdGcXHwvUIwx3EV9BKrk5fAiG9pmj5c4 k+63Prnj1+XZmElMZO5jNV1/iEpbuA== =LkZ1 -----END PGP SIGNATURE----- --Sig_/P/pgJNsB/CxxTA7Im0mlgh5--
