[uml-user] root on hostsfs fails.

[Robin Lee Powell <rlpowell@di...>]

I'm using what I think is the latest UML tutorial (there are a few
floating around the 'net).

I'm trying to do this:

linux root=/dev/root rootflags=/tmp/chroot rootfstype=hostfs

/tmp/chroot was copied and chowned from another UML boot file.

No matter what I do, I always get:

Kernel panic: I have no root and I want to scream

rlpowell> cat /tmp/chroot/etc/fstab
#/dev/ubd0 / ext2 defaults 0 1
none    /       hostfs defaults 1 1
proc /proc proc defaults 0 0

Any ideas?

This is now fixed; went from the version of UML in Debian testing to
the version in Debian unstable, which is:

    User Mode Linux v2.4.26-3um

Now, however, it consistently hangs at:

    System time was Fri May 20 17:46:47 UTC 2005.
    Setting the System Clock using the Hardware Clock as reference...

Any ideas?

Wonderful!  Thanks.  Found it, and it works.
