su does not work in rescue.service for ExecStart
The default value of ExecStart
in /lib/systemd/system/rescue.service
is:
ExecStart=-/bin/sh -c "/sbin/sulogin; /bin/systemctl --job-mode=fail --no-block default"
This doesn't work if your root
account is locked --- it'll give this error:
Cannot open access to console, the root account is locked.
See sulogin(8) man page for more details.
Press Enter to continue.
Instead, I want it to drop to the shell of a regular user that has sudo
as root
privileges.
This is what I have done:
# we don't want to edit the main file
# so make a copy in /etc and edit it there
cp /lib/systemd/system/rescue.service /etc/systemd/system/rescue.service
# then change the ExecStart line to look like this
ExecStart=-/bin/sh -c "/bin/su - homie; /bin/systemctl --job-mode=fail --no-block default"
I am testing this by powering off an external USB drive and and booting. It'll go into rescue mode but it still give that same above error.
What am I doing wrong?
And yes, I know I can use the --force
option of /sbin/sulogin
to force it to open a root shell even if the root account is locked but I do not want to do this for security reasons. I want it to drop to a regular user shell.
