Hello list,

I can't get pacman to ignore read-only files via the the NoUpgrade and/or the NoExtract config options.

I have several Arch Linux LXC (managed via LXD) containers, with several read-only files mapped into those containers for convenience. For example, to have a single resolv.conf for all containers, I configured the following in LXD:

devices:   resolv_conf:     path: /etc/resolv.conf     readonly: "true"     source: /root/containerfiles/resolv.conf     type: disk

Now the problem is, when I want to run upgrades in containers, the pacman check for disk space fails with:

error: Partition /etc/resolv.conf is mounted read only

According to man pacman.conf, setting "etc/resolv.conf" in NoUpgrade should *in theory* get around this problem for my understandings, but it somehow doesn't. Also setting both does not work:

NoUpgrade   = etc/resolv.conf NoExtract   = etc/resolv.conf

Am I missing something out here? Is there any way to accomplish what I want or do I really have to work with a pacman hook here which copies the read only mounted file to the original place after a package upgrade?

Thanks & kind regards,

Marcel Menzel

Following up: Commenting out "CheckSpace" in pacman.conf will lead to the desired behavior. Is this considered worth reporting as a bug in the bugtracker?
