I am trying to manage the "Match User" and "Match Group" sections in
sshd_config.
I am not sure what I don't have quite right.
It works if I have only one section, but when I try to manage multiple
sections it doesnt work.
I get warnings on the first pass with the delete sections, because they
don't exist yet.
$ cf-agent -KIf ./sshd_sftponly.cf
!! The promised line insertion ( ChrootDirectory /sftp-jail/%u)
could not select an edit region in /tmp/sshd_config
I: Report relates to a promise with handle ""
I: Made in version 'not specified' of './sshd_sftponly.cf' near line 62
!! The promised line insertion ( ForceCommand internal-sftp) could
not select an edit region in /tmp/sshd_config

-> Edited file /tmp/sshd_config
and it adds the sections to the config
$ cat /tmp/sshd_config
Match User restricteduser
Match Group sftponly
on the second execution I get no errors
$ cf-agent -KIf ./sshd_sftponly.cf
-> Edited file /tmp/sshd_config
but only one section is edited.
$ cat /tmp/sshd_config
