Linux reservation home folder permissions for image owner.

[Dmitri Chebotarov <dc...@gmu.edu>]

Hi

There is a small issue with home folder permission for image owner on Linux reservations.
Capturing process doesn't delete image owner's home folder when a Linux image is captured (Linux.pm:delete_user() mentioned '# Do not use userdel -r, it will affect HPC user storage for HPC installs'. )
Then when owner makes reservation his/her home folder has incorrect permissions which breaks login (xrdp doesn't work and SSH gives error about accessing home folder). 
The fix is simple - become sudo and run chown on /home/username folder, then logoff/login.

I think it will make sense to execute 'chown $username /home/$username' during reservation process to make sure that current user has full access to home folder.
This problem only affects image owner user. Looks like it only happens when image update involves adding a new users (ie. install a package which adds new user account).

Agreed.  Could add/append this command to the $useradd_string command string.
