[Spacewalk-list] Invalid cross-device link error

[Pierre Casenove]

I keep working on my issue,
Here is a working strace, when downloading package osad from spacewalk
client web repository:
stat("/data/satellite/redhat/1/b4f/osad/5.10.34-1.el5/noarch/b4f797216885818ee51d9a01813422a1/osad-5.10.34-1.el5.noarch.rpm",
0x7fff36060790) = -1 ENOENT (No such file or directory)
stat("/data/satellite/redhat/1/b4f/osad/5.10.34-1.el5/noarch/b4f797216885818ee51d9a01813422a1",
{st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
rename("/data/satellite/redhat/1/stage/osad-5.10.34-1.el5.noarch.rpm",
"/data/satellite/redhat/1/b4f/osad/5.10.34-1.el5/noarch/b4f797216885818ee51d9a01813422a1/osad-5.10.34-1.el5.noarch.rpm")
= 0
chmod("/data/satellite/redhat/1/b4f/osad/5.10.34-1.el5/noarch/b4f797216885818ee51d9a01813422a1/osad-5.10.34-1.el5.noarch.rpm",
0644) = 0

It seems that spacewalk-repo-sync behaves differently when a local
repo is used (ie file:///var/...) or a web repo.
With a local repo, the rename is called on the source name to the dest name.
With a web repo, the repo is created in /MOUNT_POINT/redhat/1/stage
and then renamed, which is much better.

Could you please help me with this one? I'm really stuck and have no
idea where to look at in the code.

Pierre
