Yes, a.out binaries still work fine - the FreeBSD version of netscape is still a.out, for example - you will need to make sure you install the a.out compatability libraries during the upgrade, though. A binary upgrade is likely to be much easier than a source code upgrade for such a jump (make aout-to-elf, or whatever the makefile target was, may well have rotted since 3.0-REL). > Please, if anyone is aware of any other issues, let me know (config > file differences, etc). If you want to be 100% certain, work through your kernel config file and make sure all of the options are still documented (and with the same syntax) in LINT. The biggest gotchas whenever you upgrade a system is updating /etc: mergemaster(8) helps enormously with that, though.
