HFS+ was just an extension to HFS, which goes back to the System 2 days. HFS suffered from a number of limitations which made in unsuitable on volumes larger than 2 GB.

That depends on your shell. Bash works that way, but zsh does not; at least not by default as far as I know.

I see what you mean now, but I must say that I really don't agree with these non-ECC horror stories. You have much bigger problems if you have memory corruption.

The ones you mention are American companies and thus does not have to follow European law.

ZFS does not require ECC memory more than any other file system. I have no idea where you got that from.

So how is FreeBSD able to license ZFS by simply importing it into the source tree and Apple is not?

How could the RAM be responsible for damaging a file between the time it was written to disk and when it was read from disk?

The point is that there are good file systems that can detect when the storage unit fails, give you an alert and allow you to restore the file from a good backup. Without this feature the corrupted file will just get backed up like any other file and eventually replace the good backup.

At least you would know that the file was corrupted, so that you could restore it from a good backup.

The problem with bit rot is that backups doesn't help. The corrupted file go into the backup and eventually replace the good copy depending on retention policy. You need a file system which uses checksums on all data block so that it can detect a corrupted block after reading it, flag the file as corrupted so that you can restore it from a good backup.

I have this problem more frequently with desktops and servers during power outages.

What do you mean by init? There's still a binary called init if that's what you want. And RHEL 6 used Upstart, but I don't know if that's more init than Systemd. So yes in theory you can since you have access to the source code and can modify it any way you want. This will be cumbersome in practice.

That's true, although I would suggest that you also don't improperly shut down your laptop. :-)

It's Gnome 3.8, which is a good desktop in my opinion. But you take some time should try it out yourself.

Any file system should be fine. Go with the default if you're not sure you want something else.

It is 3.10. But keep in mind that this is only where Red Hat essentially forked their version. Each minor release adds major changes to the kernel, including both hardware support and new features.
