Module Name: src
Committed By: rin
Date: Sun Mar 8 06:23:18 UTC 2020
Modified Files:
src/etc/etc.sun2: Makefile.inc
src/sys/arch/sun2/conf: GENERIC
Added Files:
src/sys/arch/sun2/conf: NFS
Log Message:
sun2 kernel is restricted to ~2MB due to bootloader.
It seems that working kernel should be more smaller.
Strip off most kernel options, and provide by kernel modules.
Also add GENERIC kernel for NFS root instead of FFS.
