I agree that anaconda Fedora installer isn't very good (to say the least).
But I'd also say that what you're asking it to do is rather advanced and I
think unnecessary.
"necessary" is prerogative of human, not program. Fedora installer
makes me fill like I'm disabled person. )
Comparing to open suse installer - it is worser then ever.
I mean apart from what the installer can support, in your case (I've
read some of your other partitioning messages) it seems unnecessary.
The idea that you have to treat SSDs as fragile has not withstood the test
of time. In fact, SSDs are widely regarded as /more/ durable than HDDs now.
I've bought my hdd 3-4 years ago (don't remember exactly). Newer ssd
may be better.
My one.. I just want to pay 1 day for installation and then keep this
for years. So why not to think twice and make setup that will be just
better in resource utilization?
IIRC, about any SSD post 2011 should be quite durable... so a Samsung
830 or similar vintage should have no particular worries about longevity.
And I don't know of any Qubes Btrfs users (incl. myself) who employ special
drive geometries or other complicated setups to save SSDs from wear.
Okay, now you may memorize me ;) I always attempt to get some extra
customization from my PC. =)
With that said, I have found it impossible to get anaconda to do anything
with LUKS+Btrfs beyond the default, one-partition setup.
Even specifying a
single existing Btrfs root partition is probably going to fail.
I've got installed Qubes 3.2 for testing purposes on a hdd only w/o
encryption just right now w/ root on btrfs. It is possible via fedora
installer, but I except:
*) had to kill efi partition - not to confuse stupid asus n56vz bios
*) bootloader configuration - I had to install grub2 non efi rpm
manually + install grub mnually . Thanks - documentation is pretty
accessible from mobile phone - I install grub rarely so was in need on
some reference for my dual boot. :)
IMHO, the only way to get Btrfs running with Qubes is to do a plain install
with the
Btrfs option
btrfs is just a switch for default partition type for new partitions I guess.
Yes, its just a switch, which anaconda will proceed to handle entirely
wrong should you have anything 'fancy' specified (existing Btrfs+LUKS,
multiple volumes, etc). Usually what happens when I specify Btrfs with
anything but defaults is anaconda forgets encryption step... Whoops!
---Anything else must be done as adjustments after installation.
I prefer to do customisations at install time. After testing I'll
records btrfs stats, kill this one Qubes install, repartition and
encrypt by hands, then just make installation eat my point of view.
That's annoying, but I spent lots of time w/ computers to give up on
just ugly installer. ;)
Just thought I'd offer my experience in case it saves you some time and
effort.
BTW, besides not supporting raid 5/6 (no big deal for me), the other
downside for using Btrfs is still free-space reporting. It still isn't
done in a realistic manner, IMO... you may need to keep 30-60GB free
space at all times to avoid the fs going into read-only mode.
