@Dan Hello,
So our investigation found that this change was introduced with commit https://github.com/xcp-ng/sm/commit/00637dd52e845d6016add9718fc9cc694aec9f0d
It was aimed at EXTSR in particular, it appear that the first SR to be plugged is the one choosing the mode of sr-mount since util.makedirs also create the parent directory with the given mode.
I have created a card for the issue on our side.

I'm seeing a recurrence of the snapshot_of / hidden-disks issue after patching to xapi-26.1.16-1.2 (both hosts, rebooted). Unusual element this time: snapshot-fixer.py dry-run flags ~260 VDIs across the SR that all cite a single OpaqueRef which resolves to no VDI (xe vdi-list | grep <ref> returns nothing). Holding off on rewrite until I understand whether that single-dangling-ref pattern is safe, given the set appears to include base VDIs of legitimate snapshots.
Full technical detail and questions posted on GitHub: https://github.com/xcp-ng/xcp/issues/844.
@AtaxyaNetwork Merci pour tes recherches !
Oui "cd_label" serait cool comme ajout au plugin ce qui permet sur les distro type Fedora/Redhat de ne pas avoir de boot_command à gérer
