Subject: Re: Alternative FS OS Installs (btrfs, zfs)





I thought I'd read there was some native encryption in btrfs
      added at some point, but seems they indicate to just continue to
      use luks here too.  All in all, I'm trying to remove these
      "layers", otherwise I'm pretty good with just sticking to my
      current mechanisms.  This is what they seem to indicate doing, but
      now I still need either efi or grub partitions again.  Ugh.


https://wiki.archlinux.org/index.php/Dm-crypt/Encrypting_an_entire_system#Creating_btrfs_subvolumes

    Encryption is a big component for me, with raid and volume
    management secondary.  Simplicity would be nice, but manageable
    complexity would be nice as well, as this has worked for me for the
    past 10 years.


    The whole gpt thing even with a regular sata ssd I just simply could
    not get to work with arch, which was a bit disappointing.  I really
    want to make arch work, it always sounds great, but I've never made
    it work for me long enough I haven't gotten annoyed with some form
    of brokenness too.


    Maybe I'll just stick to mbr+mdadm/luks/lvm/ext4, still seems the
    best, most reliable thing going as far as linux is concerned.

I have tried both, and the built in nature of
        BTRFS has sold me over ZFS. Both worked great for me, but BTRFS
        is batteries included.  That being said, I pretty much
        exclusively use Arch which tends to have much more current
        everything than Ubuntu.

Anyone
            using "alternative" file system methods like btrfs or zfs to
            boot with?  Nothing seems too native, but can be made to
            work it seems, just wondering if this is one of those
            "should do" vs. "can do".


            The notion of something that can do raid, encryption, volume
            management, and snapshot features is attractive, but I've
            always layered mdraid, luks encryption, lvm, then ext atop
            that.  This has been pretty solid when the ssd's don't die
            3-6 months later, even with aligning partition to block
            boundaries and such, trim, etc.  I'd love to have one single
            encrypted partitions I can use volumes within for the os
            mounts, btrfs and zfs in theory do most of this now.


            How well is really the question...


            Commentary appreciated!
