NetBSD/mac68k is now using ELF as its native object file format in -curr
ent.
With the COMPAT_AOUT_M68K kernel option, all your old a.out binaries should
still work. Note that a.out versions of ifconfig(8)
and route(8) will not work due to some structure
alignment problems.
A NetBSD/mac68k ELF snapshot is available in the mac68k
snapshot
area of the ftp server. Also available are
instructions
for upgrading to ELF from this snapshot or from source.
