Currently, There is one line in /usr/lib/tmpfile.d/legacy.conf(this is in
package systemd),
"L /var/log/README - - - - ../../usr/share/doc/systemd/README.logs"
This line will create an link to "${datadir}/doc/systemd/README.logs" during
boot,
and ${datadir}/doc/systemd/README.logs is in package systemd-doc. So there will
be dead link when systemd-doc is not installed.
So that's why I create another legacy-doc.conf packaged into systemd-doc
Then legacy.conf and README.logs should be placed into the same
package. I would suggest that README.logs just goes into main systemd
package. (the other option is placing legacy.conf into systemd-doc,
but that file is not doc-specific, and should stay in systemd package,
especially if more entries are added to it).
The solution is also good. But package "${docdir}/systemd/README.logs" in
package systemd may make things more complicated.
since in bitabke .conf, ${PN}-doc is before ${PN} in PACKAGES, and FILES:${PN}-doc =
"${docdir} ...". we need to adjust the sequence,
and may have influences to current list of files and directories that are
placed in a package.
So maybe this patch is more simple and reasonable, and will not have other
impact.

The symlink in legacy.conf use relative path. but for oe, when
VOLATILE_LOG_DIR is true, /var/log is a link to /var/volatile/log, so
/var/log/README need link to ../../../usr/share/doc/systemd/README.logs,
while VOLATILE_LOG_DIR is false, /var/log is a dir, so /var/log/README
need link to ../../usr/share/doc/systemd/README.logs.
After change it to absolute path, checking of VOLATILE_LOG_DIR is not needed.
That's ok, but can you make fixing the path to an absolute one a
separate, second commit then?
if use solution in this patch, it is better they are in one commit. I can
update description more detail.
You could also explore using -Dcreate-log-dirs=false via EXTRA_OEMESON
Thanks. I had do some research about turn off CREATE_LOG_DIR,
if turn off CREATE_LOG_DIR, " /var/log/journal/" will not be created.
By default, VOLATILE__LOG_DIR = "yes", this change will have no
influence, since we will remove content under /var/log.
if VOLATILE_LOG_DIR set to "no", the current default behavior will be
changed, log will saved from persistent to memory. our default
Storage set to auto, if " /var/log/journal/" not exist, the log will
save in memory /run/log/journal. Refer [1]. So I did not try to turn
off it in case current default behavior is changed.
