mount: append inverting options for mount.<type>
fstab:
server://foo /mnt/foo nfs user,exec
The mount(8) does not append the option "exec" to /sbin/mount.<type>
helper's command line. This is no problem when executed by non-root
user as it reads the options from fstab only.
.. but when executed by root (UID=0) then the mount.<type> helper
follows the command where the "exec" option is missing. This is bug.
original version (strace output):
execve("/sbin/mount.nfs", ["/sbin/mount.nfs",
"sr.net.home:/mnt/store", "/mnt/store", "-o",
"rw,nosuid,nodev,noauto,user"], [/* 21 vars */]) = 0
fixed version:
execve("/sbin/mount.nfs", ["/sbin/mount.nfs",
"sr.net.home:/mnt/store", "/mnt/store", "-o",
"rw,nosuid,nodev,noauto,user,exec"], [/* 21 vars */]) = 0
