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
