We're gonna try for just 64-bit versions of new releases. This lines up with the trend for increasing desire for systems with 4GB+ of RAM, and is also somewhat reflected in our download numbers. (Yes, 64-bit addressing takes up only a little more space & were not counting 32-bit PAE.)
Of course the key is not forcing too much work upon admins to change platforms or architectures to get a new version of ZCS at present, but still balancing benefits on our side of the house for phase-out down the line. Each platform we support requires hours of build & regression testing time, which of course equals money and effort better spent on other things. (Maybe someone in the community will produce a SLES 11 32-bit, should be an easy def file.) Ended with ZCS 6.0:
OpenSUSE 10.2 32-bit Predict ends when ZCS 6.5 released:
Debian 4 32-bit
Fedora 7 32-bit
SLES 10 32-bit
RHEL 4 32-bit
Ubuntu 6 32-bit
Mac 10.4 32-bit Predict ends when ZCS 7.0 released:
Debian 5 32-bit
Fedora 11 32-bit
SLES 10 64-bit
RHEL 4 64-bit
RHEL 5 32-bit
Ubuntu 6 64-bit
Ubuntu 8 32-bit Supported Into the future:
RHEL 5 64-bit
RHEL 6 64-bit
Ubuntu 8 64-bit
Ubuntu 10 64-bit
SLES 11 64-bit
SLES 12 64-bit
Mac 10.5 32-bit
Mac 10.6 32/64-bit
The Unknown New OS 64-bit
As you can see in the below path SLES actually has more choices, but forces architecture change if going SLES 11. (ie: Optional SLES 11 64-bit till 7.0)
SLES 10 32-bit @ 5.0 > SLES 10 32-bit @ ZCS 6.0 (no change, ends 6.5)
SLES 10 64-bit @ 5.0 > SLES 10 64-bit @ ZCS 6.0 (no change)
SLES 10 32-bit @ 5.0 > SLES 10 64-bit @ ZCS 6.0 (architecture change)
SLES 10 32-bit @ 5.0 > SLES 11 64-bit @ ZCS 6.0 (platform & architecture change)
------------------------ > SLES 11 64-bit @ ZCS 6.0 (new install)
------------------------ > SLES 10 64-bit @ ZCS 6.0 (new install, recommend 64-bit)
------------------------ > SLES 10 32-bit @ ZCS 6.0 (new install, not recommended, ends 6.5)
(I'd of course personally love a SLES 10 32-bit @ ZCS 5.x or 6.x so that you could do the install.sh -s platform changes easier.)
Had we stuck to our 'just 64-bit for new releases' rule without 32-bit for Debian & Fedora, one would have to do both a platform and architecture change just to try ZCS 6.
And unlike SLES 10, there isn't a "no change" choice that continues into ZCS 6.5 since were removing F7 & D4 (ie: Forced F11 & D5 with ZCS 6.5)
Fedora 7 32-bit @ 5.0 > Fedora 7 32-bit @ 6.0 (no change, ends 6.5)
Fedora 7 32-bit @ 5.0 > Fedora 11 32-bit @ 6.0 (platform change)
Fedora 7 32-bit @ 5.0 > Fedora 11 64-bit @ 6.0 (platform & architecture change)
------------------------ > Fedora 11 64-bit @ 6.0 (new install)
------------------------ > Fedora 11 32-bit @ 6.0 (new install, recommend 64-bit)
------------------------ > Fedora 7 32-bit @ 6.0 (new install, not recommended, ends 6.5)
Debian 4 32-bit @ 5.0 > Debian 4 32-bit @ ZCS 6.0 (no change, ends 6.5)
Debian 4 32-bit @ 5.0 > Debian 5 32-bit @ ZCS 6.0 (platform change)
Debian 4 32-bit @ 5.0 > Debian 5 64-bit @ ZCS 6.0 (platform & architecture change)
------------------------ > Debian 5 64-bit @ ZCS 6.0 (new install)
------------------------ > Debian 5 32-bit @ ZCS 6.0 (new install, recommend 64-bit)
------------------------ > Debian 4 32-bit @ ZCS 6.0 (new install, not recommended, ends 6.5)
