That's the essence of what's being discussed here
laptop/desktop/workstation installs default to ext4 and experienced
users/sysadmins those that generally know what lvm is with all it's
bells and whistles and want to use it will choose it during
installation.
Those that claim that novice end users have no problem using LVM I
want them to perform just this very simple case of two person
sharing what ever data between themselves could be family photo
music video and what not.
Partition an external connected HD that you got laying around with LVM.
Hand that drive to the novice end user running GNU/Linux on
laptop/desktop/workstation ( if he's not you can just insert a live
cd and boot from it ) and ask him to copy a single file to that
drive no more no less.
Take note on how many obstacle are in the users way from performing
this simple yet commonly used test case.
Repeate process this time with ext4 only for comparison.
After performing this simple test case and you have gathered the
necessary data revisit the topic of how easy it is for the novice
end user to use LVM and if he will ever use what ever tools we
provide him with to take advantage of all the features LVM brings
and if it makes sense to default to it.
This is a silly straw-man. No one[1] formats external HDs with
anything other than MS-DOS FAT. Fedora changing the default for the
main hard disk will not make any difference to this case of your
contrarian user giving away LVM-formatted USB drives.
Rich.
