[PATCH] tools: (Actually) drop libsystemd as a dependency
Posted by Andrew Cooper 5 months, 4 weeks ago
When reinstating some of systemd.m4 between v1 and v2, I reintroduced a little
too much.  While {c,o}xenstored are indeed no longer linked against
libsystemd, ./configure still looks for it.

Drop this too.

Fixes: ae26101f6bfc ("tools: Drop libsystemd as a dependency")

Found when trying to build Xen in XenServer with libsystemd absent from the
chroot.

LGTM, but my knowledge of systemd is very limited.

Thanks, Roger.

Thanks.  TBH, this is all M4/autoconf, rather than systemd.

dependency is what I can't be sure about.

Thanks, Roger.
