XFS Capability

As of this document's author-date (2019-03-21), the AMIgen7 scripts now support the optional creation of AMIs with XFS filesystems.

Usage

The default behavior for AMIgen7 remains creating EXT4-based AMIs. This ensures that any downstream projects that rely on – or even merely "expect" – the prior, EXT4-based behavior, will continue to function without further modification. For those wishing to create AMIs with XFS-based filesystems, it will be necessary to:

  1. Invoke the DiskSetup.sh script with the additional filesystem flag and specify the xfs filesystem-type. In other words, add -f xfs to whatever method you use to invoke the DiskSetup.sh script.
  2. Invoke the MkChrootTree.sh script with the additional script-argument, <FSTYPE>. Doing so allows the explicit selection of ext4 – as well as ext3 (not tested) – or xfs. In other words, when calling the MkChrootTree.sh script, do so as any of:
  • MkChrootTree.sh <BLOCKDEV>
  • MkChrootTree.sh <BLOCKDEV> ext4
  • MkChrootTree.sh <BLOCKDEV> ext3
  • MkChrootTree.sh <BLOCKDEV> xfs

In either case, the requested filesystem-type is case sensitive. The scripts will fail if you specify EXT4, EXT3 or XFS instead of ext4, ext3 or xfs (respectively).
