comment Does setting the system time back impair logrotate operation?
Thanks for your answer Patrick. On another embedded system using the same board I also sync time with NTP so I don't have to worry about logrotate getting screwed up. The problem with this one specifically is that it doesn't even have an ethernet connection available. I know deleting the status file just makes logrotate recreate one next time referring to 1970, but I wonder if it gets restarted again it will not rotate properly because the clock got backwards even during "1970".

comment Why my partitions don't show the right capacity on a 4096 byte physical block hard drive?
Yeah.. I used "right" as an irony, because the simple existence of the switch misleads the user into thinking it should be used to specify the correct size to match the physical block.

Thanks for the input @psusi. What I did to solve the problem was indeed to repartition without the -b switch and start my first partition on sector 4096 to guarantee alignment, making both fdisk and mkfs stop complaining about performance degradation due to physical sectors misalignment. But I was still wondering why the system was interpreting the number of blocks as 512 byte long when the "right" switch was used.

comment Interesting Secure Copy Behavior
You're welcome! Think of scp as a secure ftp (there's an exact equivalent in the form of sftp, which is also part of openssh). What it does is to copy a file to or from a remote server through an encrypted channel. You wouldn't ever need the extra overhead of encryption and network connection if you are doing things locally, where you have complete control over the system.
