+    <braunr> at least having the same api in the debian package and the git
+      source would be great (in reference to the large store patch ofc)
+    <youpi> braunr: the api part could be merged perhaps
+    <youpi> it's very small apparently
+    <antrik> braunr: the large store patch is a sad story. when it was first
+      submitted, one of the maintainers raised some concerns. the other didn't
+      share these (don't remember who is who), but the concerned one never
+      followed up with details. so it has been in limbo ever since. tschwinge
+      once promised to take it up, but didn't get around to it so far. plus,
+      the original author himself mentioned once that he didn't consider it
+      finished...
+    <youpi> antrik: it's clearly not finished
+    <youpi> there are XXXs here and there
+    <braunr> it's called an RC1 and RC2 is mentioned in the release notes
+    <antrik> youpi: well, that doesn't stop most other projects from commiting
+      stuff... including most emphatically the original Hurd code :-)
+    <youpi> what do you refer to my "that" ? :)
+    <braunr> "XXX"
+    <youpi> right
+    <youpi> at the time it made sense to delay applying
+    <youpi> but I guess by nowadays standard we should just as well commit it
+    <youpi> it works enough for Debian, already
+    <youpi> there is just one bug I nkow about
+    <youpi> the apt database file keeps haveing the wrong size, fixed by e2fsck
+    <pinotree> youpi: remember that patch should be fixed in the offset
+      declaration in diskfs.h
+    <youpi> I don't remember about that
+    <youpi> did we fix it in the debian package?
+    <pinotree> nope
+    <youpi> you had issues when fixing it, didn't you?
+    <youpi> (I don't remember where I can find the details about this)
+    <pinotree> i changed it, recompiled hurd and installed it, started a perl
+      rebuild and when running one of the two lfs tests it hard locked the vm
+      after ext2fs was taking 100% cpu for a bit
+    <pinotree> i don't exclude i could have done something stupid on my side
+      though
+    <youpi> or there could just be actual issues, uncovered here
+    <youpi> which can be quite probable
