Hi all,
I've been recently searching through internet for a possible solution
for this but so far without success and I'm still not sure if it is even
possible. Basically what I'm trying to do:
During system boot, after the network-online target I want to execute a
script which changes the current target ( or put simply just to boot in
another target, not in the default multi-user.target).
So here goes what I've done:
1. Create a service and put it in the network-online.target:
/etc/systemd/system/change-target.service:
/[Unit]//
//Description=Change Target //
//Wants=network-online.target//
//After=network-online.target//
//
//[Service]//
//Type=oneshot//
//ExecStart=/tmp/script.sh//
//TimeoutSec=60s//
//
//[Install]//
//WantedBy=network-online.target/
2. Create two new targets:
/etc/systemd/system/a.target:
/[Unit]//
//Description=A Target//
//Requires=multi-user.target//
//After=multi-user.target//
//AllowIsolate=yes//
//Conflicts=b.target/
/etc/systemd/system/b.target:
/[Unit]//
//Description=B Target//
//Requires=multi-user.target//
//After=multi-user.target//
//AllowIsolate=yes//
//Conflicts=a.target/
3. The contents of script.sh
blah blah: do some work and based on that do either
systemctl isolate a.target || systemctl isolate b.target
Note I've also edited the multi-user.target to depend on the the
change-target.service by putting the latter in the former's wants and
after sections. I've tried many things and every time it failed. The
problem is that the systemd should "wait" for the execution of script.sh
before continuing with the boot process.
The question is - is what I'm trying to achieve even possible or systemd
should boot in a certain target before changing to another one ? If
possible please advise what I'm doing wrong since I'm pretty lost..
