[lmi-commits] [lmi] master 565e243 10/10: Write log files elsewhere

[Greg Chicares]

branch: master
commit 565e2435cfe65b2e48865d66e586b31a60a28c68
Author: Gregory W. Chicares <gchicares@sbcglobal.net>
Commit: Gregory W. Chicares <gchicares@sbcglobal.net>

    Write log files elsewhere
    
    Write logs to /srv/cache_for_lmi/logs/ because it an "identity mount"
    representing a location on the host system. Formerly, logs were written
    to directories inside a (possibly nested) chroot, and preserved by
    copying them to the host (by nesting-dependent commands).
    
    Add a common timestamp suffix to these logs' names, and archive them.
