Indeed.

Not at the time but I have done so now.  I attach an updated patch
as the Gentoo provided patch expected the missing.h file to be in
a different place than where it is located in the Debian source.

As the kernel in unstable (4.0.8) does not have the newest syscalls
wired up on Alpha (the one in experimental does have them) I further
patched systemd to have the Alpha syscall numbers for memfd_create
and getrandom (that patch not attached here as waiting for the upload
of linux 4.1 to unstable is a better solution).  That built
successfully and now installed into an Alpha with a self-compiled 4.1
kernel (to get those latest syscalls).

For some reason systemd can't automount the disks from /etc/fstab (it
wasn't doing that before so this is not new to this systemd version)
and drops into a shell, at which point I can mount the disks and it
continues to boot up fine after that.  So seems to be working.

No.  I do not agree with the github terms and conditions so do not and
will not have an account there.  Unfortunately, it seems one to has to
have an account to file a bug report on github.

Cheers
Michael.
