Need Clarity: why need gspt.SetProcTitle(os.Args[0] + " server") when server run

[xiaods]

I am reading the source code for k3s, I don't know why need this line
gspt.SetProcTitle(os.Args[0] + " server")

anyone know it and give some hints.

I'm try build cross compile based on AMD64 image. but it block by this line:
https://github.com/k3s-io/k3s/blob/master/scripts/build#L106

CGO_ENABLED=1 "${GO}" build -tags "$TAGS" -ldflags "$VERSIONFLAGS $LDFLAGS $STATIC_SQLITE" -o bin/containerd ./cmd/server/main.go

CGO_ENABLED=1 will block cross compile. so I search and found only gspt.SetProcTitle use C func.

CGO_ENABLED=1 go build -trimpath -tags "apparmor seccomp selinux netgo osusergo" -ldflags "-extldflags -static -X main.gitCommit=v1.0.2-0-g52b36a2d -X main.version=1.0.2 -w -s" -o runc .

K3s must be built with CGO_ENABLED; doing otherwise is not supported.

k3s/scripts/build

Lines 105 to 106 in 535a919

	echo Building server
	CGO_ENABLED=1 "${GO}" build -tags "$TAGS" -ldflags "$VERSIONFLAGS $LDFLAGS $STATIC_SQLITE" -o bin/containerd ./cmd/server/main.go

The reason for calling setproctitle is discussed at #2014
