and have some questions and comments. i'm 5-year linux user.

at first - NetBSD instalation is very EASY - i mean easy not
"click-easy" like commercial linux distr.. where you think it's easy but
in fact don't understand anything of it.

i used sysinst only for creating partitions, then newfs and untarred
manually. the hardest think

my questions (please delete points you don't want to ansfer for)

1) there is no /etc/inittab in netbsd. i found /etc/ttys making partially
it's function to respawn processes but how to respawn processes not for
console? is /etc/ttys right place to put pppd nodetach on serial line (i
have leased line with 33600 modem, chatscript and pppd config already
works in linux, and i found netbsd pppd almost identical to linux)

2) why it is so fast :)?
especially - disk transfer from UDMA/66 disk (dd if=/dev/wd1d of=/dev/null
bs=64k count=5000 give me 26MB/s, and 23MB/s while doing 2 cp processes
on first disk)
i have (now) STANDARD generic kernel, while in linux i have -mpentiumpro
compiled kernel with latest ide-patches etc.. and i'm getting 21MB/s on
unloaded system maximum.

3) why there is no write stalls :) ?
it is very uncomfortable in linux when copying large files. netbsd is
quite responsible even of heavy disk load including writes.

4) i've got my netbsd binaries broken (downloaded by friend who didn't
check sums). not i'm downloading sources and want to recompile NetBSD.

is it possible to easy recompile it all with -mpentiumpro -O2
(excluding pkgsrc for now) and make resulting gcc defaults to -mpentiumpro
(as i have in linux)

5) for what is all this strange option for ffs like cylinder size, groups
etc. etc. etc.
for at least 10 years there's no drive with real geometry. how to turn off
this "optimization" in ffs or it does not matter?

why there is so many seeks when cp large files making maximum 3MB/s
copying speed. can it somewhere be set to delay writes little more to get
longer writes?

read performance is excellent even with many concurrent processes

6) how good (stable) is lfs. i found lfs being much faster than lfs
(with 1048576 stripesize) both reading and writing. will it as good 
with about 80-90% filled disk (so cleanerd would be activated some time)
can lfs be used on root partition

7) is anything bad in such partition config:

a: most space
b: needed swap space
h: /boot space where kernel will be placed (max 10MB)

as i had in linux?
