optional user dir

[l15k4]

This helps me starting sftp server that can be used right away. Since atmoz/sftp does not allow a user to write to the "base" ftp folder, it is not easy to deploy sftp server that can be written into without any action... I tested it both with :

• dir: "" which resolves into sftp:test::: in /etc/sftp/users.conf which seems to be valid and working
• dir: "uploads" which results in creation of that dir and allows the user to write to it

After so many years and this still here...

I had the same issue with writing permissions:

PermissionError:` [Errno 13] Permission denied

And after this changes solved my problem.
Now if I access to the bash of the pod I can see:

bash-4.4# ls -la /home/sftpuser/uploads
total 12
drwxr-xr-x    2 sftpuser users         4096 Jun  3 15:19 .
drwxr-xr-x    3 root     root          4096 Jun  3 15:16 ..
-rw-r--r--    1 sftpuser users            9 Jun  3 15:19 test.txt

This changes should be merged.
Thanks @l15k4 !

@flyingklop @hsychla @KilianDargel maybe one of you could have a look? I came across the same issue.

Edit: created a new chart which also fixed this: https://github.com/sj14/helm-charts/tree/main/charts/sftp-server
