I managed to create an rh72u buildroot on rh80 by liberal use of
# export LD_PRELOAD=/lib/libnss_files.so.2; apt-get -c
/var/lib/mach/states/.../apt.conf -f install ...
to work around the GLIBC version problems
apt-get: relocation error: /lib/libnss_files.so.2: symbol
_nss_files_parse_{pw,gr}ent, version GLIBC_2.0 not defined in file
libc.so.6 with link time reference
which would occur every time an RPM script would invoke useradd or
groupadd.
I suppose the following patch would also work (untested):
