While LVM obviously add some complexity, the comparison with git is really not fair. If you understand git then you can certainly understand LVM with an extremely small effort.
There are only two/three LVM concepts you need to know:
1. Physical partitions: your real, good old disk partitions
Apologies for just making you fully understand LVM against your will.

Talk about oversimplification! He's going to have to read a lot more documentation to get even the simplest operation done in LVM.
Really, if if the desire is just to to move or resize partitions, it's probably best to use gparted and skip LVM entirely. Not many people actually need the additional features that LVM offers.

I must be a genius then.
The only thing I do besides remembering the above is type the following:
lv[tab] --help
That's 15 minutes extra but it's only 15 minutes and it does not happen often.

The key LVM feature for me is: no reboot interruption(s) distracting me at the worst possible moment. If that's not considered important then yes LVM should be skipped.

Yes, if your machine is up and running then you have recourse to "ten minutes of googling". If it won't boot because the initrd doesn't recognize the LVM setup and just falls over in a heap (rather than doing something helpful like, I don't know, displaying a list of volume groups and volumes and letting you choose which to mount as /) then everything becomes a lot more uncomfortable.

That's not really LVMs fault, but the fault of the init root your distro supplied. That early-boot stuff gets rewritten en-masse regularly and then shipped to you when it still has lots of undiscovered bugs probably means you're the running the regression-guinea-pig version of your favoured vendors' distro.

Are you really suggesting that with only your previous post, 10 minutes of googling, and the output lvm --help, that epa (or typical Linux users) will be able to easily reconfigure their lvm setups?

I think he is right. I did this last week. I did a backup, and half an hour later I had all my partitions + filesistems resized, and it was my first try at lvm.
Of course it depends on how you describer a typical user, but I think the statement is true for a user that knows what a filesystem/partition is and need to resize them.
