DietPi-Software | Skip setting file permissions globally after each install

[JJGO]

Every time I reboot the machine the permissions on /mnt/dietpi_userdata/dokuwiki are reset from www-data:dokuwiki to dietpi:dietpi.

I need the folder to have user www-data for the web server to edit files and the group to include other users such as the syncthing daemon.

I could automate the permission change on startup but my question is why is this happening and if it is expected behavior.

Thank you

@JJGO
Many thanks for your report.

Nope permissions reset on user data is not expected on reboot, only when doing a dietpi-software install. But we are already thinking to skip that as well.

Could you please paste:

cat /DietPi/dietpi/.install_stage
cat /boot/dietpi/.install_stage
lsblk -f

I see, I correlated with the wrong thing then. Pretty much all my reboots were triggered from some install so it makes sense. I tested and a single reboot does not change permissions.

The output is

$ cat /DietPi/dietpi/.install_stage
2
$ cat /boot/dietpi/.install_stage
2
$ lsblk -f
NAME        FSTYPE LABEL  UUID                                 MOUNTPOINT
mmcblk0                                                        
├─mmcblk0p1 vfat   boot   5DB0-971B                            /boot
└─mmcblk0p2 ext4   rootfs 060b57a8-62bd-4d48-a471-0d28466d1fbb /

Is there a way to tell dietpi-software to skip some folders when reseting permissions on install?

Ah okay yes then this is expected. Currently there is no way to skip this, besides manually editing the script. But this would be reset on update etc. so I think currently your best way is to re-set permissions on boot.

However I will turn this issue into a feature request to skip setting permissions for the whole user data dir on each dietpi-software install, but instead set them individually only for the dirs/files required for the currently installed software title.
