Hi,
I am working on creating a rootfs tarball for alpine linux to be used
as base for things like docker images. Currently all alpine release
iso images are created as non-root, with some help from fakeroot.
I do have a problem with the rootfs image. The problem is that package
manager (apk-tools) runs the install scripts in a chroot. This is
because we need `/bin/busybox --install -s` to run relative the temp
root. chroot(2) will fail in fakeroot with permission denied.
I need a way to install the busybox symlinks relative a root. I know
`/bin/busybox --install -s <DIR>` but that will install all the
symlinks in a give dir instead of <DIR>/usr/bin <DIR>/sbin etc.
Possible solutions:
1) Add a -p flag to indicate that DIR is a root prefix instead of
target directory for all links.
/bin/busybox --install -s -p DIR
2) Add an flag to print all install paths to the applet.
/bin/busybox --print-paths
I want avoid a custom patch for busybox, so what would be an acceptable
solution for upstream busybox? Other ideas?
Thanks!
-nc
PS. There is a fakechroot but it appears to be very gnu libc centric and
does not build with musl libc.
