...

There is no reason to modify getty@.service for implementing tty1 to get --no-clear, please don't touch this file. I prefer we stay as close as possible to upstream (even if people insist on getting --no-clear on tty1)

getty@.service is modified to match the pre-systemd behavior for tty*, which was not to deallocate the VT. (Because once deallocated, /dev/vcs* no longer what was on it) getty@tty1.service is then subsequently added to implement the pre-systemd tty1 semantics.

...

Don't replace macros (%makeinstall) which are doing what is expected to do.

They don't do the same on all distros, which is why %makeinstall is a bad idea. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Except systemd expects on VT deallocation to flushback scrollbuffers (see 6ea832a20700f5282c08c70f38422c6ab290a0b5 ).

I'm packaging systemd for openSUSE where this macro has a define value. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Reading through the bugzilla report, the way it looks is that Fedora wanted that behavior for its distro. systemd itself does not expect it (say, for finishing a log file or something). But ok. So how is the changeset supposed to look? We certainly need a getty@tty1.service, to remove TTYVTDisallocate. As for getty@.service, having both --noclear and TTYVTDisallocate is a confusion. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
