You can set MAKEFLAGS=-s in your shell environment, or add -s to the current value of MAKEFLAGS if you have one. That should work. IMHO this would be good practice only in a universe where everything would always work right. In our own, this means anytime something goes wrong, you'll have no context for it. If you don't mind having to change flags and rerun whatever make command failed, when something fails, to find out what went wrong where, it's your call. -- Clifton -- Clifton Royston -- clift...@iandicomputing.com / clift...@volcano.org Custom programming, network design, systems and network consulting services ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
Re: GENERIC make buildkernel error / fails - posix_fadvise

chflags -R noschg /usr/obj/usr

It's much faster to do:
/bin/rm -rf ${obj}/* 2 /dev/null || /bin/chflags -R 0 ${obj}/*
/bin/rm -rf ${obj}/*
If I could just add one thing here, for those who might be tempted
to immediately cut and paste that elegant command line:
Consider, how does that command evaluate if the shell variable obj
is not set, and you're running that literal string as root?
A: You will very systematically wipe your entire server, starting
at the root, and doing a second pass to get any protected files you
missed.
I'd recommend something safer like approximately this (untested):
if [X${obj} != X -a -d ${obj}]; then cd ${obj} (rest of cmds);
fi
Sorry for the wasted bandwidth, for those to whom it was obvious,
but anybody who has ever had to clean up after a junior admin's
attempt to do something a little too clever will appreciate why I'm
posting this.
On the efficiency front, for the core file deletion operators, I've
had good results with this trick (requires Perl and makes use of
its implicit-operand idioms):
find ${obj} | perl -nle unlink
If rm had an option to take files from standard input, or if
there's another program I'm not aware of which does this, it
could serve as the right-hand side of this.

Thanks for making it clear that my comment was unclear. :-) I had meant a program which reads the input file list as xargs does and operates directly on its operands as xargs does I'm very familiar with xargs, and have used it in many a shell script. However, it has the weakness that it will end up doing many invocations on the executable operand, as it batches up the input into command line arguments. I don't know to what extent that overhead would compare to the other sources of overhead discussed earlier, or the overhead of executing a Perl interpreter opcode per input, but I'd guess it's higher. I think I tried that specific comparison of xargs rm vs. perl -nle unlink once, some years ago, for some kind of temp file cleanup, and found the latter was faster. I don't have any numbers though, and if I did they'd be long out of date. -- Clifton -- Clifton Royston -- clift...@iandicomputing.com / clift...@volcano.org Custom programming, network design, systems and network consulting services ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
Re: FreeNAS to Custom FAMP Server

I wouldn't use it for something like this yet, particularly if you're not yet very familiar with FreeBSD. If you were going by the 9.0 release schedule page on freebsd.org, I regret to say that you should ignore it - it's not being kept up to date with the actual status and slippage of the release. Treat 9.0 as unreleased until you see the official announcement of its release. The latest official release is 8.2, and I would start there. Next, having all your drives in RAID-5 under gvinum may not be the right choice or even a workable choice. That would imply that you are going to boot off the gvinum RAID-5 plex. In that case, before the OS can set up the gvinum drive, the boot loader, kernel, and the gvinum module must all be readable via simple BIOS disk reads - but with RAID-5, they won't be. Gmirror can do this, but does only simple mirroring. Possibly you would want to look at putting the drives in ZFS and setting up boot from ZFS instead. That's a more future-proof solution. Once the drive set up is selected, and the OS installed, the rest of what you want installed is pretty simple, I think, using the ports manager. For an appliance style configuration, it's possible that FreeNAS would be better for you; I'm sorry to say I haven't got around to trying it yet.
