[Lxc-users] help with root mount parameters

[atp]

Thanks to both for the replies.

This now makes sense. I've specified the rootfs.mount in the container
config, and it gets past there and boots ok. 

Just in case anyone else cares, a very handy debug log can be had by
using this command. 

lxc-start --logpriority=TRACE -o /tmp/trace.log --name my_container

It was not clear from the man page that to get the higher levels of
verbosity (DEBUG|TRACE) you need to specify an output file, rather
than just stderr. 

The autoconf maze has me befuddled as well. I tried briefly to see where
VERSION and PACKAGE_VERSION were defined but to no avail. 

In answer to Daniels question;

islab01 is an FC12 machine, running 2.6.34 (for the macvlan stuff)

[root at islab01 lxc]# grep /usr/lib64/lxc *
[root at islab01 lxc]# head config.log
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by lxc configure 0.6.5, which was
generated by GNU Autoconf 2.63.  Invocation command line was

  $ ./configure

from the trace.log
      lxc-start 1274794074.668 WARN     lxc_conf - failed to mount

for 'test'
      lxc-start 1274794074.668 ERROR    lxc_start - failed to setup the
container

So something is going awry, but I'm really puzzled as to how having read
the setup_rootfs section. Its probably not worth chasing down at the
moment.
