A "Credentials" section name in systemd.exec man page was used
both for User/Group and for actual credentials support in systemd.
Rename the first instance to "User/Group Identity"
Using `bootctl set-default @current` will set the default loader entry
to the currently booted entry as read from the `LoaderEntrySelected` EFI
variable.
Also `bootctl set-oneshot @current` will set the oneshot loader entry to
the current booted entry.
Correspondingly `@default` and `@oneshot` can be used to read from the
LoaderEntryDefault and LoaderEntryOneshot EFI variables.
… requirement for portable service images.
systemd will mount the host machine-id and resolv.conf at these
locations, so for read-only images these must exist in the image,
because they can't be created.
…otherwise try to clone it as a device node
On most contemporary distros /dev/ptmx is a device node, and
/dev/pts/ptmx has 000 inaccessible permissions. In those cases
the symlink /dev/ptmx -> /dev/pts/ptmx breaks the pseudo tty support.
In that case we better clone the device node.
OTOH, in nspawn containers (and possibly others), /dev/pts/ptmx has
normal permissions, and /dev/ptmx is a symlink. In that case make the
same symlink.
fixes#7878
currently if a stub image is directly booted, bootctl reports:
```
Current Loader:
Product: n/a
ESP: /dev/disk/by-partuuid/b0a0807d-0592-40e9-adac-3bb724e9e305
File: └─/EFI/Secure/secure-boot-4.14.8+.efi
```
Let's add a StubInfo which will be displayed by bootctl too (in a later
patch).
when an image with the stub is booted directly from UEFI, bootctl status
shows this:
```
Current Loader:
Product: n/a
ESP: /dev/disk/by-partuuid/b0a0807d-0592-40e9-adac-3bb724e9e305
File: └─n/a
```
After this change, the stub reports the image itself:
```
Current Loader:
Product: n/a
ESP: /dev/disk/by-partuuid/b0a0807d-0592-40e9-adac-3bb724e9e305
File: └─/EFI/Secure/secure-boot-4.14.8+.efi
```
b9088048b1 seems to have broke it
fstab_is_mount_point() returns `true` (1) if the mount point exists and `false` (0) if it doesn't exist.
the change in b9088048 considered that if fstab_is_mount_point() returns 0
the mount point exists.
