| 19:12.11 | jonpry | hey detule |
| 19:12.35 | jonpry | i made some changes to initrd |
| 19:13.16 | jonpry | i'm guessing this guy was not on crack https://lkml.org/lkml/2012/4/1/123 |
| 19:14.19 | detule | do we need a new chroot binary? |
| 19:14.26 | detule | this switch_root must be dated |
| 19:14.47 | detule | should i pull one out of the arm debian that's on my phone? |
| 19:14.58 | jonpry | in theory the ABI does not change |
| 19:15.21 | jonpry | and afaict chroot is little more than a syscall |
| 19:15.24 | detule | oh switch_root is a link to busybox |
| 19:15.55 | jonpry | yeah switch_root is a complicated mess. so i decided to switch to chroot |
| 19:16.08 | detule | chroot works? |
| 19:16.15 | jonpry | no it segfaults |
| 19:16.23 | jonpry | and has no effect |
| 19:19.04 | detule | can you incorporate that initramfs init script in rootfs |
| 19:19.06 | detule | no need to chroot |
| 19:19.53 | jonpry | well |
| 19:21.01 | jonpry | we could probably combine the initrd and rootfs. but i'm sort of interested in fixing the problem |
| 19:43.08 | detule | i think i may have dropped my phone one last time this afternoon |
| 19:46.27 | jonpry | uh oh |
| 19:53.26 | detule | you'll be happy to know switch_root segfaults for me as well |

| 19:56.04 | detule | sorry kernel panics |
| 19:59.19 | jonpry | yeah the nice thing about chroot is that the kernel can survive |

| 20:00.11 | jonpry | here is the init i am using http://pastebin.com/0bGni0CV |
| 20:00.34 | jonpry | see i tried to do that special thing to catch a switch root failure and drop to shell |
| 20:00.40 | jonpry | but it doesn't work |
| 20:00.57 | jonpry | afaict this is because switchroot dies in the very last step which is a chroot |
| 20:01.09 | jonpry | and by that time it has already zonked the initrd |
| 20:02.42 | jonpry | also msm_i2c is not building so no microp and the shell is lame |
| 20:15.47 | detule | what's the chroot implementation? |
| 20:15.50 | detule | set_fs_root? |
| 20:30.19 | jonpry | not too sure. in the kernel i think its ./fs_struct.c:void chroot_fs_refs(struct path *old_root, struct path *new_root) |
