systemd: need better handling of linux-pam

Currently (in the systemd staging branch) we fork the linux-pam package from aports to build it with systemd support enabled... we (currently) do this for many packages. linux-pam is a special case: we don't change the pkgver to always be greater than the version in aports. Presumably this is done because a few things in aports(?) have an explicit dependency on a specific version of linux-pam. For other forked packages, we use the version 999$pkgver. The problem with linux-pam is that sometimes the aports version is installed, breaking UIs, etc in systemd-based installs. The aports non-systemd version of linux-pam is installed if the pkgver in pmaports is less than the pkgver in aports.

Ideally we wouldn't need to fork this package, and aports would be able to build a systemd version of it. Since that's still a ways off (if ever) from happening, I wonder if we could do something else to handle this better.

changed milestone to %initial systemd support

Does this work?

1. Change the package name of the pmaports linux-pam systemd version, to maybe linux-pam-systemd or ???

2. set provides=linux-pam in the apkbuild

3. keep pkgver same as linux-pam in aports, so explicit deps on a linux-pam version work (??is this right??)

4. extra-repos/systemd/postmarketos-base-systemd depends on linux-pam-systemd

Do you have any examples of aports that explicitly depend on a given linux-pam version?

Ok so apparently I made that part up... nothing in Alpine aports seems to have an explicit dependency on a specific version of linux-pam.

@calebccff why did we do this in systemd/linux-pam, instead of using a pkgver=999$ver like we do in other forked packages?

# MUST be kept in sync to avoid accidentally pulling in the alpine version
# we hard depend on this exact version in postmarketos-base-systemd. When updating
# the package here it must also be updated in postmarketos-base-systemd.
