UPSTREAM: RHEL-only

BREW: 33929331

When qemu-ga was introduced to RHEL-8, we used the qemu-guest-agent
|
|
|
c687bc |
from RHEL-7 as base.
|
|
|
c687bc |
|
|
|
c687bc |
In RHEL-7, qemu-guest-agent is built as standalone package.
|
|
|
c687bc |
It's built as "qemu-ga", hence the "qemu-ga" folders.
|
|
|
c687bc |
|
|
|
c687bc |
For RHEL-8, that should have been renamed to qemu-kvm, but I missed it.
|
|
|
c687bc |
Renaming those folders to /etc/qemu-kvm is a no go today, because
|
|
|
c687bc |
users might have populated the /etc/qemu-ga/fsfreeze-hook.d folder.
|
|
|
c687bc |
|
|
|
c687bc |
So, in order to make qemu-ga -F works in RHEL-8, a link is being
|
|
|
c687bc |
created in the expected place, pointing to the real one.
|
|
|
c687bc |
|
|
|
c687bc |
Also, fsfreeze-hook opens up the fsfreeze-hook.d on the same PATH where
|
|
|
c687bc |
it is stored. However, it doesn't follow symlinks. In order to fix this,
|
|
|
c687bc |
I had to change it to make sure it follows the link.
|
|
|
c687bc |
|
|
|
c687bc |
An option would be to also link the fsfreeze-hook.d folder, but I choose
|
|
|
c687bc |
not to do so as it creates a permanent/visible change in users
|
|
|
c687bc |
environments. The downside is to keep another downstream-only change.
