We have a minor problem with uploading a fix. E2fsprogs currently
FTBFS on stable, due to bug #707996, whose root cause is #708061.
Personally, I blame glibc (#708061) for once again making a
library-visible API change. (If they didn't want programs to use
__secure_getenv, they shouldn't have made it visible.)
However, the decision was to fix it by forcing a reconfigure and
rebuild of all affected packages --- which in the case of e2fsprogs
FTBFS, requires a rebuild and re-upload of util-linux (#707996). This
has happened in unstable, but it hasn't happened in stable.
There is (almost) nothing I can do to work around this problem in
e2fsprogs, since the problem is that e2fsck.static is linking against
the blkid library found in util-linux, and it is the blkid library
which is referencing the symbol in glibc which has vanished in a puff
of greasy black smoke.
The (almost) referres to something really, REALLY, horrible which I
could do, which is to use the antique version of the blkid library
found in the e2fsprogs sources, from before we transferred it over to
util-linux. I could only do this for e2fsck.static, but that would
mean that e2fsck and e2fsck.static would be using different versions
of the blkid library. Or I could do it for e2fsprogs as well, but
then e2fsck and mke2fs would be using a version of blkid that hasn't
been updated for several years, and which will have all sorts of bugs
and lack features added since the move to util-linux.
The really right answer is to rebuild (it doesn't even require a
source-level change, since I believe the configure script should make
the right thing happen once we build with the glibc with the
gratuitous ABI change) and then reload util-linux.
What say the release team?
