LVM : xfs vs ext

I am (again) trying to make a full disk encryption installation of Trisquel (8).
I just gave up on the method explained on libreboot.org (https://libreboot.org/docs/gnulinux/encrypted_trisquel.html). During installation the 'install software' step failed.
Now I am trying to use the automated method provided by the Trisquel installer, but I face two 'unknowns':
1) It doesn't seem that I can manually create a swap partition. Will it do that automatically?
2) The manual at libroboot.org and others instruct to use the ext4 file system, but the Trisquel installer uses the xfs file system.
What would you advise?
I am a member!
During installation the 'install software' step failed.
Which one is the 'install software' step? How did it fail?
I've never used the installer for T8, so someone might have better answers...
1) Normally when you start the installer you have an option for how you want to install, and one of the options will say something like "do something else." Choose that option and you can create your own partitions.
2) Use ext4 unless you have huge storage (>16TB).
I believe you are referring to Trisquel's graphical installer, which does not propose full-disk encryption (only encryption of the home folder with eCryptfs, whereas GNUbahn is talking about a the text installer. I believe he follows the instructions on https://trisquel.info/en/wiki/full-disk-encryption-install
Anyway, the text installer has the equivalent of "Do something else": it is called "Manual" according to a screenshot in the manual linked above.
XFS is said to be faster with large files, hence Trisquel's default for /home. A few MB is "large" in this context. Its largest drawback is: it cannot be shrunk. So, if you under-size an adjacent partition, it will not be easy to take space from the partition with XFS: you would have to copy its data elsewhere, delete it, extend the adjacent partition, recreate a (smaller) partition with XFS (or not, if you change your mind) and copy the data back onto this new partition. So, well, you had better not under-size the adjacent partition.
You believe well.
For now I used the XFS 'provided' by the graphical installer, but at some point in the future I hope to figure out how to make it work with ext4.
Thanks for the explanation.
