Alpine aarch64 chrootable rootfs

August 31, 2018 — BarryK

I posted awhile back how easy it is to create an Alpine musl-based chrootable filesystem folder:

At the time, I created i686, x86_64 and armv7 root-filesystems.

Now that I am embracing aarch64, want a rootfs for compiling static executables. Hence:

After expansion of the tarball, instructions are inside. You will of course need to be running a aarch64 host OS, in my case on the new Rock64 board.

I compiled squashfs-tools 4.3, and it needs a patch for musl:

For good measure, I also applied all the patches from Debian. My rootfs does not have zlib-dev, so had to install that:

# apk add zlib-dev

...the rootfs has the Alpine apk package manager in it.
