I am very interested in shedding the fat in illumos. There are several things that need to be addressed:
- We have some horrible dependencies which aren't optional, such as Net-SNMP (which needs to be built as both 32-bit and 64-bit), trousers (probably needs both 32-bit and 64-bit as well) and perl. Each of these things have their own set of dependencies which will likely need to be bi-arch as well. In the case of perl we’re primarily using it for one daemon – intrd – which should be rewritten in C. - As I mention above, we’re still clinging on to 32-bit with much of the userspace being 32-bit only. Making the utilities and daemons that are currently 32-bit only 64-bit is not a huge change, but adding an option to disable building of the 32-bit stuff entirely is an enormous change touching hundreds of Makefiles. - As alluded to in other replies, we have a dependency on the GNU userland. In the past this was because most of our utilities did not support GNU extensions, but we are mostly past that now. Now it’s down to us missing things like our own version of stat. We can pull that in from FreeBSD, so I don’t think that’s much of a problem.
