SSH key handling

pmbootstrap can copy SSH keys to the device during the install step.

If the config file option ssh_keys is set to True (it defaults to False), then all files matching the glob ~/.ssh/*.pub will be placed in ~/.ssh/authorized_keys in the user’s home directory in newly-built images.

Sometimes, for example if you have a large number of SSH keys, you may wish to select a different set of public keys to include in an image. To do this, set the ssh_key_glob configuration parameter in the pmbootstrap config file to a string containing a glob that is to match the file or files you wish to include.

For example, a ~/.config/pmbootstrap_v3.cfg may contain:

[pmbootstrap]
# ...
ssh_keys = True
ssh_key_glob = ~/.ssh/postmarketos-dev.pub
# ...
