Even this article title says "POTENTIAL" release. I am not even sure it is signed? They are still doing QA, it will be a week or two before GA Before you rush to 7.0 after 6.5 - things you are going to have to learn because they change everything: systemd replaces init.d grub2 replaces grub xfs is now default over ext4 filesystem ( many, many people dislike systemd, it is somewhat anti-linux in nature ) No more easy…

XFS is a dealbreaker for me. Nothing but bad experiences with that particular FS, especially when the filecount goes up.

No more easy editing/understanding grub.conf True, the grub2 config is horrible. No more easy to understand /etc/init.d It's a bit more complicated, but not too bad: Instead of "/etc/init.d/thing restart" you type "systemctl restart thing" Instead of chkconfig --list, you type "systemctl list-dependencies" Writing the equivalent script with systemd is much cleaner with less hacks, particularly for launching as differ…

I'll wait for more benchmarks to be certain but this database test of the 3.10 kernel (which 7 uses) of XFS vs EXT4 is not promising:

If I were a large enterprise I'd reconsider CentOS. RedHat's lack of a commitment to the customer's experience in favor of RH's personal design preferences smacks of Oracle-ism. Anything they develop they immediately force on their users, and you have to just accept it rather than use it optionally. It's less easy to get away from those kind of changes versus something more open like ubuntu/debian (and I have no love for debian). And then there's the whole secret kernel patches and backported "features"... Then again i'm a dirty hippie who prefers Slackware, so maybe i'm too Linux-libertarian for today's enterprises.

So use ext4, it isn't as though ext4 isn't included :)

Note that of course you can still choose to use EXT4 when installing 7

Thanks for posting this. That's what i was expecting. Does any of that really improve my day? Nope. In fact most of it makes it worse and adds friction. More cogs turning in different directions. Will keep our devops stuff on CentOS 6.5 for at least another 4 years...

Will keep our devops stuff on CentOS 6.5 for at least another 4 years... What if someone needs one of the newer packages provided by RHEL7?

They can use the software collections to install it.

As excited as I am for 7.0 I highly dislike the systemd and grub changes. I'll wait for benchmarks before I decide to go to 7.0 or fully switch my stack to Debian

debian is also switching to systemd

and using grub2

You don't like systemd but it's probably time to accept the fact that it has "won". Most major distros including Debian is switching to it so it will get harder and harder to avoid. Might as well make the effort to learn it now.

Technically I don't have to accept it until 2020 ;-) (and FreeBSD has declared they will never use it, which to be fair is easy for them to declare since they cannot use it because it requires posix) (correction: not posix, cgroups and udev)

Well, I did mean Linux when I said "distros". :P

RHEL pretty much is the standard for enterprise-y distros. I'm pretty confident they weighed the XFS decision very heavily, and in the end chose it for good reason.

In fact, here's an article on the SUSE blog from a year ago discussing why XFS is a great choice for enterprise:
