[systemd-devel] Journalctl --list-boots problem

[Martin Townsend]

Hi,

I'm trying to get journalctl --list-boots working but it always shows
the current boot

# journalctl --list-boots

I'm using persistent storage and I'm sure I have /var/log/journal
setup correctly because if I specify the directory I get the list I'm
after

# journalctl -D /var/log/journal --list-boots

I'm looking through the code and in sd-journal.c it should add the
/var/log/journal in the function add_search_paths.  Any ideas why it's
now working unless I specify the directory explicitly. I'm building
systemd using Yocto (thud) release.

# journalctl --version
systemd 239
+PAM -AUDIT -SELINUX +IMA -APPARMOR +SMACK +SYSVINIT +UTMP
-LIBCRYPTSETUP -GCRYPT -GNUTLS +ACL +XZ -LZ4 -SECCOMP +BLKID -ELFUTILS
+KMOD -IDN2 -IDN -PCRE2 default-hierarchy=hybrid

Here's the end of the configure task in case it helps
