From 4b376d1ad1b46408bc59d949c277991a9b5035eb Mon Sep 17 00:00:00 2001 From: Karel Zak Date: Thu, 27 Oct 2016 15:30:20 +0200 Subject: [PATCH 177/178] mount: append inverting options for mount. on "users" If you call mount(8) as root, then we need to append inverting options (if specified by fstab) for "user" and "users" to /sbin/mount. command line, because for UID=0 mount.nfs follows command line rather than the fstab setting. This has been originally implemented by commit a4c0cc75ff9744299f108c259efab1bd30c8007a for the old mount(8). The same feature is supported by libmount, unfortunately for "user" only. We need the same also for "users" to be backwardly compatible.
