Hi Yann,
Le 22/06/2016 à 21:07, Yann E. MORIN a écrit :
> Currently, both the sysv-like and custom skeletons are managed in a
> single package.
>
> However, for the custom skeleton, we basically do nothing, except for
> a few symlinks for the /lib directory aliases, and a few checks about
> merged /usr.
>
> OTOH, for the default (sysv-like) skeleton, we do a lot more things,
> like tweaking the issue, the hostname, setting the root password and so
> on...
>
> Furthermore, we're soon gonna have a skeleton for each kind of init
> system, be it sysv-based or systemd.
>
> So, it makes sense to offload the custom skeleton management to its own
> package.
>
> We change the way we check for the merged /usr readiness, from checking
> at make parse time, to a configure command. This has virtually zero
> impact, since the skeleton is the very first package to be "built", so
> its configure commands are the very first to be run. It however slightly
> cimplifies the .mk as we need not enclose the parse-time checks inside
^
s/cimplifies/simplifies/
> an ifeq-block to check if the package is enabled.
