Does a filesystem check initiated from /etc/fstab auto-repair?

We have a Raspberry Pi located at a location where it may experience frequent power loss. I'm trying to make it scan, and repair (if necessary) a filesystem every time it boots up, in case the power loss causes FS corruption. The filesystem in question is ext4, but it is NOT the root filesystem.



It seems that I can do what I want by using tune2fs -c 1 /dev/sdX#, and setting /etc/fstab's Filesystem Check Order to 2 for that partition. What I'm not sure about is what it does when it detects problems. Does this automatically fix them? Will it stop booting, and wait for someone to confirm that it should fix things?



The Pi is headless - there's no one to confirm anything.

          How many registers does an x86_64 CPU actually have?

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
