All questions are related to i386 architecture where applicable.
1. Can current bootblocks boot kernel from level 1 ffs ?
(I'm not going to convert my *extremely* stable FS's while seeing
fs-related panic reports on mailing lists, I still use 0.9 bootblocks)
2. I noticed that libgcc.a for NetBSD's gcc is much smaller than
libgcc.a installed by stock gcc-2.6.0. (17KB vs 120KB). Can our
libgcc.a be used instead of original libgcc.a when linking object files
generated by gcc-2.6.0 ?
3. I need some hint on how code size/code speed tradeoff influences
overall system performance in NetBSD. Would it be benefitial
if I could compile all code 5% smaller than usual and 8% slower
( when cpu bound, locked in memory) on machine with 16MB memory
and 1 swap partition on SCSI disk,running XFree,everything linked dynamic ?
( I'm prepared to build entire system)
4. Looking into current kernel sources I found that madvise and mincore
system calls are still unimplemented. Are there any plans to implement
Thanks in advance,
