The issue seems to have started between http://people.debian.org/~joeyh/d-i/images/20090930-19:15 and http://people.debian.org/~joeyh/d-i/images/20091024-21:59/ which is unfortunately a rather large range. Apart from the version currently in testing binutils seems to have had one other version uploaded in that period (2.19.91.20091003-1) but in the absence of snapshot.debian.net I don't think I can get hold of it. mklibs doesn't seem to have changed since early August which seems to rule it out. > > The symbol _nss_files_parse_sgent is provided by /lib/libc.so.6 and > > required by /lib/libnss_files.so.2.

I believe it does: $ objdump -T tmp/netboot-gtk/tree/lib/libc.so.6 | grep nss_files_parse 00056a30 g DF .text 000002ed GLIBC_PRIVATE _nss_files_parse_pwent 0007c880 g DF .text 000003cf GLIBC_PRIVATE _nss_files_parse_sgent 00055900 g DF .text 0000030e GLIBC_PRIVATE _nss_files_parse_grent 0007c3f0 g DF .text 000003d3 GLIBC_PRIVATE _nss_files_parse_spent > > Comparing a manual "make build_netboot-gtk" with the daily-build logs > > (either my local ones or the build server ones), I see this which seems > > odd: > [...] > > That is indeed strange and should be looked into, but I doubt it is related > to the mklibs failure as neither libc6 nor libnss-files are "extraudebs". Originally I wondered if one of the extra udebs was introducing an extra dependency on the symbol which I wasn't finding because the extraudebs dir is deleted after it is used.

Indeed, it seems to have resolved itself now. Thanks, Ian. -- Ian Campbell 'Scuse me, while I kiss the sky! -- Robert James Marshall (Jimi) Hendrix
