在ubuntu Linux下搭建了svn服务器，工作正常，svn的档案respository存放在挂载的一个fat32分区中，apache的用户www-data也加入了plugdev组，能够正常读写svn的档案。

svn server build on ubuntu, apache, work fine. and svn respository is on mounted fat32 partition, and have add apache’s user www-data to plugdev group, so apache can r/w svn respository.

但是当在fat32分区中使用svn客户端，checkout或者update文件的时候，却发生了错误：

but when use svn client on fat32 partition, failed:

原来，在Linux中，有些文件是不允许非所有者owner用户修改的（不知道是核心功能就禁止这样，还是一些软件按照这个规则来实现的？），即使当前用户有读、写权限。现在遇到的这个例子就说明svn客户端就是这样，所以我们必须把svn要操作的文件（.svn/entries什么的）的所有者owner改掉。

it’s because, in linux, some file are not write able to user who is not its owner, althought the operate user have write priv, this is a example. so to make svn run right, we must change owner of mounted fat32 partition.

然而挂载的fat32分区还无法修改owner，那就只能通过修改/etc/fstab文件来实现了：

it seems that we cannot change owner of mounted fat32 partition, so we can only modify fstab file. open /etc/fstab, change the line

to / 改为

vfat是分区格式（fat32），utf8是分区的字符集iocharset，umask是挂载时不分配的权限，gid 46时组“plugdev”，uid 1000就是我使用的用户fwolf。

vfat is partition fstype, utf8 is iocharset, umask is privilege not give when mount, gid 46 is group “plugdev”, uid 1000 is me — fwolf.

现在重新mount这个分区，所有分区上的文件的owner就是用户fwolf了，这也是我日常使用的用户，现在再来使用svn客户端就一切正常了。

then remount the partition, the all file on this partition is owned by fwolf, and user fwolf use svn client finely.

不过这样虽然解决了问题，但是如果多用户同时使用一台主机的同样一个fat32分区，还是无法解决，多用户的话还是把分区格式转换成ext3吧，大不了以后不用的时候再转过去。

参考：
ref1, ref2-1, ref2-2

$Id$的自动修改

和windows下的客户端类似，我以前介绍过，在Linux下编辑/etc/subversion/config，添加：

就可以自动替换所有.html文件里的$Id$了。

update @ 2006-5-24
后来发现这种把仓库存在fat32分区上的方式，虽然能够正常的checkout，但是checkin/commit的时候，会出现svn无法chmod的错误，所以仍然需要把svn的仓库存放在ext3分区上，并且把目录owner设为www-data。
