Subject: dump: restore should be statically linked

Date: Mon, 17 Mar 2003 23:02:37 +0000

Package: dump
Version: 0.4b27-4
Severity: normal

The restore binary in the package is dynamically linked,
so it is no use putting it onto the restore media
(outside the dump, of course).

I tried booting the rescue system from the install cd
and mounting a backup cd that contained the restore binary (beside dump files).
Although all needed shared libraries are available in the rescue system,
they fail to resolve the symbols in the backup binary.

That may or may not also be an issue with the boot-floppies package,
and the fact that my rescue cd was 3.0r0 while restore was from 3.0r1
may also have been a contributing factor.
However, this shows how fragile the situation is and how desirable
a statically linked restore binary is.
In fact it should ideally even work for non-Debian rescue systems.

Sure, I can build my statically linked binary myself,
but it would be convenient if it were included in the binary package,
maybe as an additional executable, say /sbin/restore-static.

Subject: or there should be a static package

Date: Sat, 22 Mar 2003 01:04:44 +0000

The upstream source has an RPM spec file to produce a static package.  Probably RH then ships with a separate dump-static package containing /sbin/restore.static.  That would be useful for debian too.  (But it contradicts the debian change to the original configure.)

Subject: my thoughts on this

thanks

There are two problems with adding a static restore to the dump package.  The
first is that the binary gets a lot larger, the other is that it means I'd have
to track security updates in glibc, etc, and upload new versions of dump more
often to keep the statically linked binary from being a security issue.

My approach is to implement a "reasonable compromise" in which all of the libs
that live outside of /lib are statically linked... which right now means the
z and bz2 libs which typically reside in /usr/lib.  This results in only a 
small increase in the size of the binaries and resulting package, and if used
on a root (or recovery?) filesystem with the right library version, should work
fine even in minimal recovery scenarios.

Note, however, that the Debian installation media uses library reduction
techniques to control the size of the image, so if you want to run a binary
that wasn't part of the image at build time you need to make sure the right
library routines are available, or use a fully static binary.  Be aware of this
when planning for disaster recovery.

It's not hard to build a static version, you just need to revert my changes in
the configure script and add --enable-static to the configure call in the 
debian/rules file and the package will build static binaries.  If someone wants
to offer up a patch that makes this easier, perhaps by adding a "static:" 
target to the rules file, I could be supportive.
