Package: libc6
Version: 2.30-2
Severity: wishlist
Hi,
would it be possible to make the libc6 preinst maintainer script
compatible with busybox? Currently the preinst script calls "readlink
-m" which is not supported by busybox. Hence the following error will be
thrown:
BusyBox v1.30.1 (Debian 1:1.30.1-4) multi-call binary.
Usage: readlink [-fnv] FILE
Display the value of a symlink
-f Canonicalize by following all symlinks
-n Don't add newline
-v Verbose
I tried to prepare a patch for the preinst script but ran into a FTBFS:

Thus, I'm now reporting this wishlist bug here before further working on
a fix.
Would you be willing to accept a change that makes the preinst script of
libc6 compatible with readlink from busybox?
Thanks!
cheers, josch

Closes: 953788 954374 954393 954715
Changes:
glibc (2.30-3) unstable; urgency=medium
.
* debian/patches/git-updates.diff: update from upstream stable branch:
- Fix a defect in the PowerPC backtrace function that could cause an
out-of-bounds write when executed in a signal frame context
(CVE-2020-1751).
- Fix use-after-free vulnerability in the glob function when expanding
~user (CVE-2020-1752). Closes: #953788.
* debian/debhelper.in/libc.preinst, debian/rules.d/debhelper.mk: determine
ld.so ELF magic at build time instead of at run time to avoid using
"readlink -m". Closes: #954374.
* debian/rules.d/build.mk: unset LANGUAGE when running the testsuite.
* debian/testsuite-xfail-debian.mk: ignore signal/tst-minsigstksz-1 and
signal/tst-minsigstksz-2 on i386, they fail on i386 with an AVX-512 CPUs
due to a kernel bug. Closes: #954715.
* debian/control.in/libc, debian/rules.d/debhelper.mk: Make libcX-dev
declare a Breaks against libcX-dev-${DEB_HOST_ARCH}-cross
(<< ${CURRENT_UPSTREAM_VERSION}~). Closes: #954393.
* debian/control.in/libc, debian/control.in/main: drop Conflicts, Breaks and
Replaces against package version older than the one available in
oldstable.
