If td_contested lock were needed ,reading ts_blocked is not protected by td_contested lock,in the kernel source, why?

Actually, I've seen that and it does come close... But it didn't seem to like updating the Kernel or anything similar to the base system in the time I spent with it. Free BSD has probably one of the best methods of installing new packages with pkg_add, and pkg_add -r for grabbing them off the internet but for updates it could use some work. It won't stop me from buying Free BSD things, but it does make showing new computer users the OS a but harder.

Re: [fbsd] Re[2]: jailctl with multiple ip per jail
Hi, Oxy, Daniel, yes, i know that, but what i want is to use an existing jail with 2ip not to create additional jails.. although i dont know if it really works, but here is what i was able to google (check those mijail patches) :) place your questions on pjd@ http://garage.freebsd.pl/ pjd's mijail patce are a little bit old as they are against 5.0-CURRENT. ISTR it is usable but there were still minor problems with it which prevented the patch from being commited, but I can't pull out the details from my memory. However checking the archives would answer you for sure. Depending on what you really want to do, you may however workaround this limitation using some NAT rules.

Re: accessing NetBSD filesystem
FFS == UFS. The FreeBSD UFS is the FFS accessed through the VFS layer, but basically the format is the same. If you want to have access, from FreeBSD, to NetBSD partitions, make sure the NetBSD partitions have been formated using FFSv2 which is the port of UFS to NetBSD. There are some differences though : no ACL support nor snapshots available there. Please use NetBSD 2.x (I use 2.1 but I got a machine running current) and format the partition to be shared using FFSv2 on NetBSD. Should work fine. FFSv2 (UFS2 in FreeBSD) is not the defautl type in NetBSD 2 for now. I have not checked in current. So if you want to use newfs from NetBSD, don't forget to ask for FFSv2 (-O 2). FFS code in NetBSD's kernel contains the options required for UFS2 support. There are superblock changes in FFSv2 (UFS2). So don't use old (as in NetBSD 1.6.x) fsck on such volumes. It is possible to do an upgrade on fsck_ffs before using FFSv2 and this works fine in 1.6.x Please read the following doc : http://sixshooter.v6.thrupoint.net/jeroen/faq.html The NetBSD's current newfs man page (http://netbsd.gw.com/cgi-bin/man-cgi?newfs++NetBSD-current) makes mention of the ACL so perhaps they're supported in NetBSD-current :) -- unzip ; strip ; touch ; grep ; finger ; mount ; fsck ; more ; yes ; fsck ; umount ; sleep ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
