Re: znapzend broken on Illumos

[David Brownlee <abs%absd.org@localhost>]

It's not SmartOS specific (other than SmartOS being a particularly
nice place in which to do ZFS things :)

It's a Mojolicious issue, or rather an compatibility issue in
Mojo::IOLoop::ForkCall (used by znapzend) with Mojolicious 9.x. It's
quite nasty in that it only shows up at runtime.

Its fixed by the latest updates to p5-Mojo-IOLoop-Delay,
p5-Mojo-IOLoop-ForkCall and znapzend in the main pkgsrc repository,
but MNX Cloud run the pkgsrc.smartos.org periodically updated fork of
pkgsrc to better tailor for SmartOS.

Looping in jperkin@ on that basis as someone who would know whether
the changes to p5-Mojo-IOLoop-Delay, p5-Mojo-IOLoop-ForkCall and
znapzend could easily be pulled across :)

Thanks

David
