[Xen-devel] [RFC] removing proc-xen.mount due to systemd change

["Vasilis Liaskovitis" <vliaskovitis@xxxxxxxx>]

Hello,

It is possible for systemd services to check for dom0 detection before xenfs gets mounted by proc-xen.mount. See this systemd bug report for an example:

https://github.com/systemd/systemd/issues/6442

Upstream systemd has accepted the patch for this: https://github.com/systemd/systemd/pull/6662,

which mounts xenfs at systemd init time i.e. making /proc/xen an API file.

However the issue now is that proc-xen.mount will refuse to mount /proc/xen as it an API file system, and the service will fail. This breaks xen, as other services depending on proc-xen.mount also fail.

What is the preferred way to deal with this in upstream xen?

- We can remove proc-xen.mount completely, for systems using systemd.

- any other options?

thank you,

- Vasilis
