su: ’su root’ succeeded for string on
/dev/pts/int
Cause
The user specified after "for" just became superuser by typing the root password.
Action
If the user is supposed to know the root password, this message is only
informational. If the user is not supposed to know the root password, change this
password immediately and ask how the user learned it.
syncing file systems...
Cause
This indicates that the kernel is updating the super-blocks before taking the system
down, to ensure filesystem integrity. This message appears after a halt(1M) or
reboot(1M) command. It can also appear after a system panic, in which case the
system might contain corrupted data.
Action
If you just halted or rebooted the machine, don’t worry– this message is normal. In
case of a system panic, look up the panic messages that appear above this one. Your
system vendor might be able to help diagnose the problem. So that you can describe
the panic to the vendor, either leave your system in its panicked state or be sure that
you can reproduce the problem.
Technical Notes
Numbers that sometimes display after the three dots in the message show the count
of dirty pages that are being written out. Numbers in brackets show an estimate of
the number of busy buffers in the system.
