Bug#602286: sitesummary-client: daily error, on vserver guests

[Ronny Aasen <ronny@datapart-as.no>]

Package: sitesummary-client
Version: 0.0.66
Severity: normal

sitesummary-client mail's a daily error to root on machines that does not have /sys. 
Examples are vserver guests and chroot's 

the mail looks like:
/etc/cron.daily/sitesummary-client:
Unable to locate sysfsroot. If kernel >= 2.6.0
    Try something like 'mount -t sysfs none /sys'

And comes from running lsscsi in collect.d/system

a simple fix is to check for contents in /sys before running lsscsi
