Bug#952767: systemd: enable systemd-pstore.service by default

[Kevin Locke]

Package: systemd
Version: 244.3-1
Severity: normal

Dear Maintainer,

This morning my ThinkPad T430 failed to boot with the message:

    Error: The non-volatile variable storage is about full
    Press F1 to enter Setup.

The cause was the same as #891434: the kernel had dumped dmesg in pstore
after an oops, which created dump-type0-* efivars, which had accumulated
sufficiently to cause UEFI pre-boot to require user action.  (Luckily my
machine still boots, unlike in #891434.)

It appears that systemd-pstore.service should move these files to
/var/lib/systemd/pstore/ but the service is disabled.  `systemctl status
systemd-pstore.service` shows:

    Loaded: loaded (/lib/systemd/system/systemd-pstore.service; disabled; vendor preset: enabled)"

I confirmed the same state occurs in a fresh testing install in a VM and
was not inadvertently disabled by me or a previous update.

Is there a reason systemd-pstore.service is disabled by default?  Could
we consider enabling it to avoid causing UEFI boot issues?

Thanks,
Kevin
