Bug#369265: fai-nfsroot: fai install dies with "nfs: RPC call returned error 101"

I never said that building the nfsroot failed, as it did not for me. When I was looking for a name, I tried to make it easier for other "fai-users" to easily find a bug that covers the problem they just stumbled across. I could of course have named it "divert fails with new FHS compliant dhcp3" but then who would profit? Well maybe Thomas L. who maybe, would not have to read the body of the bug in order to fix it. People tend to look for bugs named to what they "see", and not what the solution of their problem may be. > I am not sure because it's a while since I had that, is it possible > that make-fai-nfsroot doesn't "realize" what's happening, and still > finishes successfully, and the problems leading to an error only at > install time? make-fai-nfsroot actually finished successfully, and the problem indeed occurred at install time. And guess what the message was that I saw? ;-) > Then we should also fix nfsroot to better trap errors, if possible. > It's wrong that make-fai-nfsroot ends with success but a broken > nfsroot. But maybe the rror cannot be found out easily. That's exactly the point, this was one of the bugs you cannot detect.

Bug#397784: xen-tools: xen-create-image fetches libc6-xen from ftp.debian.org
Package: xen-tools Version: 2.8-1 Severity: normal I set up xen-tools.conf with: debootstrap = 1 dist = sid mirror = ftp:///debian The mirror defined in /etc/xen-tools/xen-tools.conf is ignored when xen-create-image installs libc6-xen. Thus the installation of libc6-xen should probably be moved to the hook 20-setup-apt, just after the "apt-get update" call.

Solange in $n noch etwas drin ist, verarbeite bis zu 2 Zeichen vom
Anfang von $n. Das ist doch der klassische Trivialfall einer
while-Schleife, und es funktioniert sogar. Ich verstehe daher nicht, was
Dir daran nicht gefällt.

Dann schaue es Dir doch mal im größeren Kontext an:
} elsif (-e "$pxedir/$srchost.tmpl" ) {
- $srcfile = "$pxedir/$srchost";
+ $srcfile = "$pxedir/$srchost.tmpl";
} else {
Es wird erst auf die Existenz des template geprüft und dann eine andere
(evtl. nicht existierende) Datei eingelesen. Ich glaube hier müßten wir
mal diskutieren was der gesamte Block an sich machen soll, aber meines
Erachtens tut er nur mit dem Patch genau das was man/ich (laut manpage)
von ihm erwarten sollte.

Soso, na das wundert mich jetzt aber, denn bei mir hat er den Bug
behoben. Nur mal so wild aus dem Patch zitiert:
+if (/\.disable$/) {
+if (-f (split /\./)[0]) {
+warn "Skipping $_ as disabled host because also enabled.\n" if
$verbose;
+} else {
und dann noch:
+ if (-f "$pxedir/$hex.disable") {
+ unlink "$pxedir/$hex.disable";
+ print "removed old $pxedir/$hex.disable\n";
+ }
Es mag sein, daß Dir das nicht gefällt, aber behoben ist es definitiv,
wie Du auch aus meinen Beispielen erkennen solltest.
Soll ich den Patch nochmal zerlegen? Warum sich das schwer einbauen läßt
verstehe ich leider nicht, da ich den direkt gegen den aktuellen
SVN-Head gebaut hatte, so daß ein einfaches "patch" ausreichen sollte.
Grüße,
thpo
