I'm using shell_exec() php function to start a script in which ntfs-3g is used.
On my old server (Ubuntu 16.04) which came with ntfs-3g version 2015.3.14,
running the script with sudo worked. (Image got mounted)
On my new server (Ubuntu 18.04.2) which comes with ntfs-3g version 2017.3.23,
running the script with sudo doesn't work anymore. Later on I installed
(2017.3.23AR.4)
In the script itself ntfs-3g is started like this: /bin/ntfs-3g -o ro
/mnt/sdb1/$RestoredImage /mnt/ImageMountPoint/$2

In the process I learned that it is not smart to give the web-server user root
privileges on a script, so I set the setuid bit on the ntfs-3g binary.
And then run the script like this from php: shell_exec("/bin/bash -l -c
\"/dummy_path/anon_file.sh $Param1 $Param2 $Param3 $Param4 $Param5\"");
The outcome doesn't differ, output indicating success but no mount present.
Example (ntfs-3g[64603]: Mounted /mnt/sdb1/Restored7831991136.img (Read-Only,
label "", NTFS 3.1))

Without the debug option output gets written to syslog.
With the debug option output goes to the apache error.log
Kind regards,

There is no change relative to interactivity which I am aware of.
However distributions may have made changes.
What is the difference of behavior you observe ?

How do you start ntfs-3g ?
What log file is this ? (syslog ?)

Are you using the debug option (which prevents daemonizing) ?

What is the emulate login parameter ?
And what was the outcome ?
