Back in '77 I worked with Steve Bourne on /bin/sh (little known fact: like awk, sh was named for its inventors, 'S' for Steve and 'H' for Humbert) and was responsible for the 'done' keyword. Following that I alternately pursued computer programming, field anthropology, and general philology; I currently work for an organization that has no name in the field of complex system obfuscation.

comment How can a filesystem be copied exactly as is?
+1 I think the clue is in the failed boot message in the OP and this addresses it.

comment Using kernel cryptographic functions
I forgot to mention that I also overwrote your "signatures" and your kernel. The kernel is just a file, it has no magical properties, and if I've hacked your machine then no file is safe. To be more explicit, if you don't trust the md5sum file there's no reason to trust the kernel or any other file.

comment Real-World Use of TCP_DEFER_ACCEPT?
Hearing (3) does not guarantee that Server didn't immediately suffer spontaneous combustion after transmission but it does increase the confidence that the Server is ready to receive.

comment Accessing Pendrive in Ubuntu using Wine
If you get caught trying to work-around IT policy, no matter how stupid it may be, they can come down on you pretty hard. For "unauthorized use of computer systems" you could risk expulsion from school, firing in the workplace, and/or criminal prosecution in either. How lucky do you feel?

comment Massive, unpredictable I/O performance drop in Linux
"Low I/O performance which persists until reboot" can be a broken/buggy device that seizes the bus too often for too long which is maddeningly hard to diagnose short of swapping out hardware.

comment Should I care for applications that increase the system Load in order to prevent overheating?
The output of lm-sensors is very system dependent and will often report sensor data with approximate naming. If that is the only temperature reported by sensors it is almost certainly the CPU temperature. On AMD quad-core cpus (among others), the PCI controller has migrated onto the CPU chip from its historically separate "northbridge" chip.

If the load average (that is, number of jobs in the ready-to-run state) goes above 4, the others will just have to wait. You can't use more than 100% of a core even if there are 23 jobs ready to use it.

You might also be able to turn off a core or two and not have to reduce the clock speed. A computer that is using half its cores is infinitely faster than one that shut down because of thermal overload.

comment fstab doesn't mount after boot of a virtual machine
To amplify @iain, since mount -a works properly at some time after boot, it is almost certainly a sequencing issue. You might try adding bootwait to the fstab options as described in fstab(5).

comment Rsnapshot via SSH speed issue
You've got --bwlimit set to 16KB/sec but the rsync throttling mechanism is crude. What happens if you double that number or remove the argument altogether?
