Customizable order of operations

[hilmiller]

I think potential users of losf would be enticed to try it if there were a way to change the order of actions performed by losf. One example is starting a service that requires specific permissions and system commands run. The desired custom ordering would be something like:

Install package
Sync config files
Set file permissions
Set directory group permissions(x)
Run shell command(x)
Start service

(x) Not supported by losf, but just a thought-experiment.

Ideally in my opinion, losf would not order activity-types like services, permissions, and files. Instead, losf would order individual actions like allowing actions to have a dependency on other actions as puppet and ansible work. If losf were to get this feature, I could imagine the losf philosophy of "keep it simple" would result in something like what I've included below. A numeric "priority" value, with ties broken randomly. The lower the number, sooner losf executes it.

[ConfigFiles]
/etc/shadow                     = yes[1]
/etc/passwd                     = yes[1]
/etc/group                        = yes[1]

[Services]
hadoop-yarn-nodemanager         = on[999]
hadoop-hdfs-datanode                = on[999]
iptables                                        = off[1]

[Permissions]
/share                             = 0755[10]
/share/doc                      = 0755[10]
/etc/shadow                    = 0440[1]
/etc/hosts                        = 0644[999]
