Description Thorsten Vaupel 2012-10-27 11:34:58 UTC
Created attachment 634160 [details]
slightly modified serial-getty@.service

Description of problem:
The unit file serial-getty@.service contains the line Environment=TERM=vt102 with the intention to pass it to the environment of the new shell but it looks as if it is ignored by agetty.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. instantiate a getty for a serial line
2. log in
3. echo $TERM
Actual results:
The value "linux" is assigned to TERM

Expected results:
The value "vt102" should be assigned to TERM

Additional info:
The attached unit file which basically appends vt102 to ExecStart works for me.

Comment 1 Michal Schmidt 2012-10-29 19:05:42 UTC
agetty always overrides the TERM variable with its own logic, unless the third argument is specified. That explains why Environment has no effect.

Furthermore, I believe there's a bug in agetty. It attempts to detect the distinction between the vc and a serial line and set TERM accordingly, but it does not work as expected. I will send Karel a fix.
