Yes, the export is mountable from
other machines as well. Here is the full output of the boot including where it

Kernel panic - not syncing:
Attempted to kill init!
***END***
That's quite strange. Usually when it panic's with that message the
kernel tells you why. You could try adding printk's into the end of
init_post (init/main.c) before/after each line that tries to run init program:
printk("%s:%d\n", __FUNCTION__, __LINE__); run_init_process("/sbin/init"); printk("%s:%d\n", __FUNCTION__, __LINE__); run_init_process("/etc/init"); printk("%s:%d\n", __FUNCTION__, __LINE__); run_init_process("/bin/init"); printk("%s:%d\n", __FUNCTION__, __LINE__); run_init_process("/bin/sh"); printk("%s:%d\n", __FUNCTION__, __LINE__);
boot with "ignore_loglevel" to see if a
"printk(KERN_DEIBUG" message was suppressed. With the output
you should be able to figure out if the kernel fired up init (and its init
that's dying). Also check that the init program and libraries are all
installed on your rootfs correctly (and are for the right machine)...
So, it appears I can mount the
filesystem (or rather the kernel can...) but something is amiss after this.
