[systemd-devel] Q on serial-getty

[Ulrich Windl]

Hi!

I'm thinking of configuring a serial getty in SLES15 (systemd-234). First I found that there is no manual page describing the service, and second if I use "systemctl show serial-getty" ("systemctl show serial-getty@" does not work), I get some "funny" numbers:

...
UID=4294967295
GID=4294967295
...
MemoryCurrent=18446744073709551615
CPUUsageNSec=18446744073709551615
TasksCurrent=18446744073709551615
IPIngressBytes=18446744073709551615
IPIngressPackets=18446744073709551615
IPEgressBytes=18446744073709551615
IPEgressPackets=18446744073709551615
...
CPUWeight=18446744073709551615
StartupCPUWeight=18446744073709551615
CPUShares=18446744073709551615
StartupCPUShares=18446744073709551615
...

Obviously that number is the unsigned 64-bit representation of -1, but considering that no such service is running, the output looks quite odd.
If -1 means "unknown", why not use that string, or if it means "unlimited", why not use that string?
