Re: AW: "cvs move" command

[Matt J. Gumbley]

Pierre, Kaz and Christian - many thanks for you replies to my mail... 
since it's only a small amount of refactoring, I'll go with the 'cvs 
rtag -d' option.. Thanks. Meta-CVS sounds interesting, and I'll 
investigate it.

As far as I recall, doesn't ext3 use the same layout on disk, plus 
journalling info? ReiserFS may be better - wasn't it designed for 
different usage scenarios? http://www.namesys.com/ for more info..


Perhaps it would be better to store all the files in a database, rather 
than many-files-in-one-directory. Hashing the files across a tree of 
directories would be better, although what could you use as the hash 
key? You couldn't use file name, since in a rename/move, that'd change..?


Kind regards,
Matt
