Scott Long have committed this which will:

Jean-Sébastien Pédron [jspedron club-internet.fr] has announced that he has ported ReiserFS 3.6 (from kernel 2.6.7) to FreeBSD (with only Read-Only support this time).

Scott Long suggests to import these to base because 6-CURRENT will have a focus on the file system. I suggested that we have a directory under somewhere in the src/ tree to keep these Linux bits so we can backport their fixes more easily and it should be better for us to rip these things out when we have re-written something from scratch.

Before reporting this to the list, I would first gather enough information.

Alu’s server boxes is suffering in continued reboot when server is loaded. Because he is supporting FreeBSD by utilizing 5.3-RC1 in his production environment (and it’s moderately loaded as it is connected to the ChinaNet Backbone), and donated many devices for dedicated services of the FreeBSD China Community, I think we must help him to solve these out.

I have plugged a new kernel configuration on his box in order to obtain a (potential) crashdump and figure out what is happening. Maybe we will get it tomorrow.

Scott Long has branched RELENG_5_3 (also RELENG_5_3_BP tag) and 5.3-RC1 is coming REALLY SOON.

It’s available here, in my home directory at freefall: http://people.freebsd.org/~delphij/mfc.xml.

Please note that this is an (incomplete) MFC list for sys/ only! I baked it up manually so I don’t guarantee thet there is no mistakes, but I really tried my best to prevent so.

我在许多场合公开地发表过类似的意见，有时言辞比较激烈，有时只是委婉地反对。

这种意见，同意也好，不同意也好，我希望其他人能够把它当作一种意见，而不是某种强加于人的意志。我只是说出自己的看法，并不要求任何人接受——如果他们认为这是对的，愿意接受，我当然很高兴；但如果他们觉得我说的有道理而不愿意接受，那是他们的问题；如果他们觉得我说的没道理，我很希望看到反驳的意见。我始终相信，真理越辩越明。

其实，最关键的问题就在于，我们没有必要重新发明轮子。在阐述这个观点之前，我希望大家能够接受一个密码学界的常识，即安全不能建立在别人不知道的基础上。另一个常识是，安全总是从最薄弱的环节被突破的，不要去尝试解决最强点上的问题——因为那不解决问题。

Matthew Dillon总是给人惊奇，这是一个你没办法不佩服的人。也许他的一些话让有的人感觉不爽，也许他被一些人误解，但他是Matthew Dillon。

Today FreeBSD will have its 5.3-RC1 if there is no other problem occours. I have sent a private mail to Doug Barton about a strange issue I have in BIND9, however, it does seem to be serious enough nor it is clear to determine the impact. I may post it later on a public list.

5.3-RC1 is also the point that I can suggest you to install 5-STABLE instead of 4-STABLE because most of the show-stopping issues are addressed and being corrected.

As always, it’s available at ftp.freebsdchina.org/china_ports/delphijfork.

I have adopted all RELENG_5 features here, bind9, etc. Also the delphijfork features are retained.
