Parsing objects is risky as data could be malformed or malicious,
so avoid doing that from the main systemd-coredump process and
instead fork another process, and set it to avoid generating
core files itself.
On distros using Debian's base-passwd, the name of the group with gid 65534 is
nogroup. Currently, systemd-sysusers creates a spurious "nobody" group
systemd-sysusers[243]: Creating group nobody with gid 996
That's both confusing and redundant, as the nobody user still has primary group
65534 aka nogroup, and the nobody group simply goes completely unused.
So explicitly specify the primary group of the nobody user, and add a line
ensuring that that group exists.
This is not a problem for Debian (or Ubuntu) itself, as they add their own
version of basic.conf in their systemd build logic. But it appears on for
example Yocto/OpenEmbedded.
Assumption in edc027b was that job we first skipped because of active
ratelimit is still in run_queue. Hence we trigger the queue and dispatch
it in the next iteration. Actually we remove jobs from run_queue in
job_run_and_invalidate() before we call unit_start(). Hence if we want
to attempt to run the job again in the future we need to add it back
to run_queue.
Fixes#21458
I've seen this in `NetworkManager-1.34.0-0.3.el8.x86_64` (latest in CentOS
Stream 8 at the time of writing this message) which does not use the latest
Systemd but probably the code base is the same (see
https://github.com/NetworkManager/NetworkManager/commit/51f93e00a23fbd09f5ad96da6290bf4ca737d46a).
Before the patch:
```
libsystemd: eth0: DHCPv6 client: T1 expires in 34y 3w 6d 45min 31s
libsystemd: eth0: DHCPv6 client: T2 expires in 54y 5month 3w 3d 23h 20min 35s
```
After the patch:
```
libsystemd: eth0: DHCPv6 client: T1 expires in 3d 7h 58min 3s
libsystemd: eth0: DHCPv6 client: T2 expires in 5d 2h 26min 50s
```
same box (x86_64 system) and same DHCPv6 server.
This regression has likely been introduced by 8a8955507a.
For LTO to work, the linker has to be called with some magic sauce arguments.
And the easiest way to get those is to just let the compiler to the job for us.
