MultiROM logs

MultiROM logs everything into kmsg. Usually, when some error happens during boot, it will create /sdcard/multirom/error.txt file in which is dmesg exported. If it does not, you can reboot to recovery and get kmesg from last boot from file /proc/last_kmsg. This only lasts through one reboot.

All MultiROM's messages are prefixed with multirom, so you can just grep for that.

There is a chance that MultiROM just crashes (you'll know that when Internal ROM boots instead of the ROM you've selected). In that case, there is message MultiROM exited with status X in the kmsg. If the X is anything else than 0, it has crashed. Report this to me along with the rest of the log.
