New version of systemd introduces dropins in /etc/profile.d. This
is usually OK for most cases. But in case of using minicom to connect
to the machine, there will be unnecessary output every time you type
a command.
This is because the /etc/profile.d/80-systemd-osc-context.sh[1] is setting
PS0 with OSC 3008 standard[2]. If a terminal (e.g., minicom) cannot
deal with this OSC 3008 standard, it will just output the whole contents.
This is quite annoying.
So add a new PACKAGECONFIG, shell-profile-dropins, to allow users a choice
to disable such behavior.

Qi,
There may be other files in profile.d as well as
80-systemd-osc-context.sh. In systemd 258.x, I also see
70-systemd-shell-extra.sh. I don't think we should offer the option of
disabling install of all systemd profile.d files in order to fix
incompatibility with just one of them.
There have been changes to 80-systemd-osc-context.sh in systemd 259. We
could try backporting 705e2ef19418 ("profile/osc-context: move and
extend check for TERM=dumb") if we're not ready to update to 259 yet and
see if that resolves the issue. We may also need dd20ba74e3b4
("profile/systemd-osc-context: fix overriding of PROMPT_COMMAND") and
97ad10c9aab1 ("profile: skip setting PS0 when PROMPT_COMMAND= is
cleared"), I'm not sure.
Best regards, i
Hi Paul,
Thanks for checking upstream status.
I think you're right. The commits you mentioned above are likely to fix
the issue.
I'll double check when upgrading systemd to 259.x.
Regards,
Qi
