git-daemon無法push? - Linux

Dear all,
想請教一下各位，
我的環境是Ubuntu 10.04
我根據下列網址的步驟執行安裝並執行git-daemon-run
http://www.gaojinbo.com/ubuntu9-0-4%E4%B8%8B%E5%AE%89%E8%A3%85%E9%85%8D%E7%BD%AEgit-daemon.html
short url:http://tinyurl.com/4v3lo9w
(大致上差不多，實際上參考很多網頁的資料)

/etc/sv/git-daemon/run的執行部分修改為下面
exec chpst -ugitdaemon /usr/lib/git-core/git-daemon –verbose \
–enable=receive-pack –export-all \
–base-path=/var/cache/git/

基本上client端要clone下來都沒有問題
但是push的時候會出現幾種狀況
一時也列不出來
所以想請教一下各位，
1.因以gitdaemon的身分執行git-daemon，那base-path下的git repos資料夾
的owner是否也需要為gitdaemon? 檔案與資料夾權限開755?

2.此外 我也參考了這篇問與答的資料
http://stackoverflow.com/questions/792611/receive-pack-service-not-enabled-for-git

的答案部份
Simply run

git daemon --reuseaddr --base-path=. --export-all --verbose
--enable=receive-pack
(on computer A, instead of the original git daemon command), and the push
works.

Note that you have to then run

git reset --hard
on computer A to make it "see" the changes from computer B.

Post Script

The problem with doing a hard reset is that it overwrites whatever local
changes you had on computer A.

Eventually I realized it would make much more sense to have a separate
repository (a bare clone) that doesn't have any files in it, then have
computer B push to it and computer A pull from it. This way it can work both
ways and merge all the changes in a smooth fashion. You can even have two
bare clones, one on each computer, and push-pull between them.

但是還是搞不太定
有人可以幫我解釋一下他的回答以及用意是什麼嗎？
謝謝:)
