Re: [uml-user] self-built root filesystem failed to boot

[Han <kee...@gm...>]

thanks Steliosm.   I tried with "init=/bin/bash" but still same error.  It
seems that not anything wrong with "init" process itself, but some error
happened before that.

I just tried to build the rootfs without "--variant=buildd".  And this time
it worked.  Not sure what changed. Will play around more.
