#81756 — Bug#1062968: initramfs-tools-core: Use zstdmt instead of zstd by default

Package: initramfs-tools-core
Version: 0.142
Severity: wishlist

It would be nice if initramfs-tools-core used zstdmt (multi-threaded)
instead of plain zstd when creating the initramfs.  On my system, that
saves about 15% of the time spent building the initramfs.

The following change seems sufficient:
