switch-root: Ensure sysctl is run again after switching root#125
Merged
Conversation
Dracut normally copies all sysctl config to the initrd, but we may want to exclude platform-specific config because the initrd is shared between platforms. That config can be picked up from the OEM sysext after switching root. Signed-off-by: James Le Cuirot <jlecuirot@microsoft.com>

There was a problem hiding this comment.
I assume that this is for picking up sysctl files that are distributed with an OEM sysext, right? Is systemd-sysctl service ordered to run after systemd-{sys,conf}ext?

If you mean we could just run it once, that would be much later in the boot process than it normally runs. If you're just checking whether I remembered that ordering for the second run, I did have that initially, but Kai's changes now mean that the sysexts are merged just before switching root (i.e. before systemd-sysext.service), so that ordering is unnecessary now. |

I meant the latter. :) Thanks. |

I have tested this manually with GCE.
