Re: Add a new exec_exec_file_name RPC

[Samuel Thibault]

Hello,

Better late than never :)

I got triggered by an issue which was making both mig and gnumach fail
to build from source :) which was triggered by Svante's turning the
exec() paths into absolute, which made shellscripts' $0 always absolute.
So I rolled up my sleeves, I changes the RPC a bit to include both the
relative path and the absolute path, for their corresponding uses in
exec, tested again the transition etc. and eventually commited the
eventual patches.

Hurd Debian packages are uploaded. The corresponding libc Debian
packages are on debian-ports, they will get uploaded to sid after the
current 2.26 migration is over. Then a hurd packages rebuild will be
needed to get the whole thing rolling. In the meanwhile there should be
no regression.

For non-Debian distributions, you may want
to pick up the hurd exec_filename_ patches from
https://anonscm.debian.org/git/pkg-hurd/hurd.git/tree/debian/patches
and the local-exec_filename.diff patch from
https://anonscm.debian.org/cgit/pkg-glibc/glibc.git/tree/debian/patches/hurd-i386
at least for some time to get backward compatibility with the previous
experimental RPCs.

Thanks for all involved in this patchset!
Samuel
