I just run chkrootkit 0.45 and got this bit:
Checking `z2'... user root deleted or never logged from lastlog!
And actually 'lastlog' says that root "Never logged in". Googling for info
only yielded two results with no valuable data.
This is the only alarm showed by chkrootkit. All the rest seems normal,
and I haven't noticed any weird stuff lately either. OTOH, 'last' and
'who' show perfectly the last times I've used a root terminal.
Could this be a false alarm, or should I worry?
Thanks in advance.
