Alpine Linux updated to 3.10

Alpine Linux, a lightweight distribution notable for its use of musl libc and busybox, has been updated to 3.10. Major changes in this release include ceph, a distributed object store and filesystem, and lightdm, a cross-desktop display manager, using kernel version 4.19.53. Note that Qt4, Mongodb and Truecrypt are removed from this release. Alpine supports ppc64le and should "just work" on POWER8 and POWER9 systems; you can download bootable images.
