* Improve xfs package's maintainer scripts:
+ + Always start the daemon on package install (as opposed to upgrade).
+ (Closes: #241539)
+ Replace xfs "upgrade" flag file with two distinct ones, "install" and
"daemon-not-stopped". Create install flag file when preinst script is
invoked with "install" argument; remove in postinst, and in postrm when
invoked with "abort-install" or "abort-upgrade" argument. Create
"daemon-not-stopped" flag file in prerm script if the daemon is not
stopped with invoke-rc.d; remove in postinst, and in postrm when invoked
- with "abort-upgrade" argument. (Closes: #241539)
+ with "abort-upgrade" argument.
+ Duplicate the postinst's daemon logic in the postrm when invoked with
the "abort-upgrade" argument; this way the daemon is restarted if it was
stopped for upgrade, but the upgrade failed.

+As XFree86 puts it:
+
+ Fix sparc asm glapi initialisation in libGL when using indirect rendering
+ (GLX) (Bugzilla #923, Ferris McCormick).
+
+Also see Debian #241331.
+
+This was adapted from revision 1.22 of xc/lib/GL/glx/glxext.c in XFree86
+CVS.
+
+This patch by Ferris McCormick.
