As part of the extension I made the directory /usr/local/etc/frr owned by tc:staff
I expected this ownership to become default after each reboot.
But a reboot causes the directory to become owned by root.
This is also the case of any subdirectories.
Is this expected?
The files in this directory do stay owned by tc:staff.
Any advice to best change ownership e.g. using bootlocal.sh or better by the install script (tce.installed)?

I decided to change ownership via the install scrip (tce.installed).
if [ -d /usr/local/etc/frr ]; then
chown -R tc:staff /usr/local/etc/frr
fi/usr/local/etc/frr is now correctly owned by tc:staff.
But after a reboot /usr/local/etc/frr/ns-frr is still changed to root:root
The directory /usr/local/etc/frr/ns-frr is created once during bootup by the bootlocal.sh script.
[ ! -d "/usr/local/etc/frr/ns-frr" ] && sudo -u tc mkdir -p /usr/local/etc/frr/ns-frr/
I unzipped the /mnt/vda1/tce/mydata.tgz in tmp and in this file the permissions are correct.
tc@testapps:/tmp/mydata$ tree -pug

See the exact same behavior with version 15.0 trying the x86_64 arch.
'/usr/local/etc/frr' becomes root:root after a reboot.
This I can counter with the following in '/usr/local/tce.installed'
if [ -d /usr/local/etc/frr ]; then
chown -R tc:staff /usr/local/etc/frr
fiBut even with the 'Recurse' flag set the subdirectory '/usr/local/etc/frr/ns-frr' still becomes owned by root:root on reboot.
Only way to counter both is to also add next line in '/opt/bootlocal.sh'
[ -d "/usr/local/etc/frr/ns-frr" ] && chown -R tc:staff /usr/local/etc/frr

I found the reason. I missed to specify the directory in '/opt/.filetool.lst'. I only added the files...
If I explicitly specify the directory '/usr/local/etc/test' in '/opt/.filetool.lst' it does restore ownership correctly.
If I only specify the file(s) '/usr/local/etc/test/test.cfg' in '/opt/.filetool.lst' it does not restore ownership of '/usr/local/etc/test'.
From extracting '/mnt/vda1/tce/mydata.tgz' it appears to store also the ownership of '/usr/local/etc/test', but it doesn't...
Steps to reproduce the issue I ran into:
# Using TCL-14.0 x86 (expect same on x86_64 and also on TCL-15.0)
# verify logged in as tc (expect uid=tc, gid=staff)
id
sudo mkdir /usr/local/etc/test
sudo chown -R tc:staff /usr/local/etc/test
# verify directory created with owner tc:staff
ls -la /usr/local/etc/
touch /usr/local/etc/test/test.cfg
# verify file created with owner tc:staff
ls -la /usr/local/etc/test/
#echo usr/local/etc/test >> /opt/.filetool.lst
echo usr/local/etc/test/test.cfg >> /opt/.filetool.lst
filetool.sh -b
mkdir /tmp/test
tar xzf /mnt/vda1/tce/mydata.tgz -C /tmp/test
tce-load -wi tree
tree -pug /tmp/test
# confirm from the 'tree' output ownership of '/usr/local/etc/test' to be tc:staff
sudo reboot
ls -la /usr/local/etc/

Yeah, this is how tar behaves. Every now and then somebody runs into the same issue.

@curaga
I don't think it is tar because after 'tar xzf /mnt/vda1/tce/mydata.tgz -C /tmp/test' permissions are still as expected.
Still have to try some more to understand this behavior a bit better, but that is of later...
For now I use a workaround as part of the tce.installed script.

If a directory is not included in the archive, it will be created with defaults. So ownership will depend on who runs it, permissions on the current umask, etc.
