Hammer CLI

Last Minute Discovery: Duplicate of https://projects.theforeman.org/issues/30639, as far as I can tell

As an unprivileged user on CentOS 8.2 and Foreman 2.3.0 on a read-only filesystem, tab completion in hammer(1) has been borked by errors spewing over the command line, as can be seen by typing "hammer <tab>" on the command line:

$ hammer No permissions to create log dir /var/log/hammer.
File /var/log/hammer/hammer.log not writeable, won't log anything to the file!
environment command is deprecated and will be removed in one of the future versions. Please use puppet-environment command instead.
report command is deprecated and will be removed in one of the future versions. Please use config-report command instead.
Error: Read-only file system @ dir_s_mkdir - ~

Running "hammer prebuild-bash-completion", does not fix the issue!

After moving back to the user's home directory, this problem disappears BUT creates a '~' directory in that location,

find ${HOME}/~/
/home/sysadmin/~/
/home/sysadmin/~/.cache

Problem is with the 'mkdir' only, as it then seems to be able to create '.cache/hammer_completion.yml', if executed from the user's home directory.

BUT recreating the original conditions by removing ${HOME}/.cache (and ${HOME}/~ and returning to the read-only file system, the problem can be easily reproduced.
