This is what upstream musl does.

apk now sends progressbar to stdout instead of stderr

we need uninstall .setup*

it is tmpfs and we know it will be removed on reboot. Infact, we want
it to be removed on reboot.

ref #2893

We should show 'diff' subcommand in help text.

This is to avoid the message:
ERROR: You tried to add a non-repository package to system, but it would
 be lost on next reboot. Enable package caching (apk cache --help) or use
 --force if you know what you are doing.

but accept it for compat reasons

aterm no longer exist and 'st' is the simplest terminal

We also remove the -n option (but accept it for compat)

fixes #2540

By default we copy the tzdata file to /etc/zoneinfo and symlink to our
copy. We also purge all previously copied timezones unless -k is given.

If -i is specified, then will the tzdata apk package stay and the
symlink will point to /usr/share/zoneinfo/... instead of a copy in
/etc/zoneinfo/

Add a magic environment variable ERASE_DISKS as confirmation for
erasing disks. This is useful for scripted installs.

fixes #2863

musl uses /etc/zoneinfo/localtime

/proc/xen/capabilities can be non-existent while /proc/xen
exists.

This behaviour was seen when booting in rescue mode on
Linode.

fixes #2258

When installling the packages in new root, the update-extlinux trigger
script will be executed. We make sure this does not fail by:
 - run extlinux --install before we install packages
 - mount /dev and /proc for the chroot
 - temprorary disable grsecurity's chroot_caps
