[libvirt] [PATCH] Make the use of XDG folders variable
Martin Kletzander
mkletzan at redhat.com
Thu Oct 11 14:31:10 UTC 2012
While ago, commit 32a9aac2e04c991340b66c855a1095e4e6445e54 introduced
a change of the folders used to keep information in user home
directories. As this can still cause problems, mainly with older
SELinux policies, make this change variable with new configuration
option '--disable-xdg'.
---
Sorry for not splitting this patch, but either having the option and
not making it work or the other way around is pretty bad (and having
it in repo as a commit even worse).
