[darcs-users] spooky action at a distance: file ownerships in repository b (pristine.hashed) change after changing ownerships in repo a

[Thomas Hartman]

This is really strange, and it may be the source of a patch-tag bug I
am trying to root out.

It seems that, under certain conditions, file ownerships in repository
b pristine.hashed change after changing ownerships in repo a.

Note: Patch-Tag private repo security is handled in the happstack
layer, so unaffected, but still.

The file ownerships in repo b that change are hash files of some kind
of binary type, which are identical in both repos. However, they don't
appear to be soft or hard links.

Also I disabled the darcs cache by doing mv ~/.darcs ~/.darcs.bak

Can anybody explain what is going on?

thanks!
