Hi,
I build my uml from source with CONFIG_INITRAMFS_SOURCE configured with a
rootfs text file. I specify the init file to busybox as
file /bin/busybox /home/xxxx/busybox/busybox 755 0 0 /init /bin/sh in
rootfs text file.
But it does not work and output "kernel panic - not syncing: No init found"
error. The full boot log is followed.
Please help me, thanks.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
