JFS has never been default in Fedora.

I didn't think that I ever implied that it was.
Fedora has actually been rather limited in it's support of various filesystems. The kernel supports the different filesystems, but the installer hasn't given you the option of using XFS and JFS for your main filsystem for example.

It appears you did
"JFS does not, for a long time (even after it was the default in Fedora)"
You are inaccurate about your claim on the installer as well. XFS is a standard option in Fedora for several releases ever since Red Hat hired Eric Sandeen from SGI to maintain it (and help develop Ext4). JFS is a non-standard option.

re: JFS, oops, I don't know what I was thinking when I typed that.
re: XFS, I've been using linux since '94, so XFS support in the installer is very recent :-)
I haven't been using Fedora for quite a while, my experiance to RedHat distros is mostly RHEL (and CentOS), which lag behind. I believe that RHEL5 still didn't support XFS in the installer

"Very recent" is relative and not quite so accurate either. All versions of Fedora installer have supported XFS. You just had to pass "xfs" as a installer option. Same with jfs or reiserfs. Atleast Fedora 10 beta onwards supports XFS as a standard option without having to do anything

That is early 2008. RHEL 6 has xfs support as a add-on subscription and is supported within the installer as well IIRC.

I think dlang meant this:
"..., for a long time (even after it was the default in Fedora), LVM did not"
(I parsed it the way rahulsundaram did too - it's not clear).

yes, now that you say that ir reminds me that I was meaning that for a long time after LVM was the default on Fedora, it didn't support barriers.
