Details

libcrc32c.ko needs at least one crc32c provider (e.g. crypto/crc32c.ko or the SSE4.2-specific arch/x86/crypto/crc32c-intel.ko) to work. However, this dependency is not reported by modinfo.

This means that if libcrc32c.ko is added to the initcpio, all providers should be included as well.

I believe this is important because btrfs depends on libcrc32c. If root is on btrfs, the initcpio will not work unless crc32c or crc32c-intel is added manually.

Additional info:
mkinitcpio 0.6.3-1
This task depends upon

Nobody read this?

I am unsure how to handle this. Filesystems are not added explicitly - either all of them are added, or all which are autodetected. As neither of these modules is a dependency of btrfs, mkinitcpio doesn't know how to handle them.

Another thought here is that for complete btrfs support, you seem to need an extra hook anyway.

I suppose so, seeing as a btrfs tool has to be run in order to discover all parts of a multi-device btrfs. This is not needed for a single-device btrfs.
