Hello,
the point below has been buried at the end one of a previous thread. So
feel free to ignore it if you find it irrelevant.
With systemd-239 on linux 4.18.0 (CentOS 8.1), why does hostnamectl
--static set-hostname <name> instantly sets the transient hostname to
<name> *only* when <name> is not the current static hostname ?
Seems to me different from the caching mecanism which explained name
sync delays the other way around, no ?
Example:
# cat /proc/sys/kernel/hostname
foobar
# hostnamectl
Static hostname: toto
Transient hostname: foobar
Icon name: computer-server
Chassis: server
Machine ID: 40c61e5c178b444598b68284b02d4148
Boot ID: efd28246f1dd4a069db77e3f8f1399dc
Operating System: CentOS Linux 8 (Core)
CPE OS Name: cpe:/o:centos:centos:8
Kernel: Linux 4.18.0-147.5.1.el8_1.x86_64
Architecture: x86-64
# hostnamectl --static set-hostname toto
# cat /proc/sys/kernel/hostname
foobar
whereas
# hostnamectl --static set-hostname titi
# cat /proc/sys/kernel/hostname
titi
Thanks
