emrootfslib

Revision 4931, 17.0 kB (checked in by codehelp, 4 months ago)

* embootstrap fails if /bin/sh is not symlinked to /bin/bash (Closes:

#498495)

* pbuilder/emdebian.coreutils pbuilder/emdebian.crossd

pbuilder/emdebian.gpe pbuilder/emdebian.gtk pbuilder/empbuilderlib
pbuilder/emrootfslib: migrate POSIX functions out of empbuilderlib
and into a new shell library, emrootfslib, that is checked for
bashisms each build. Migrate deboostrap suite scripts into
/usr/share. Add experimental pbuilder/emdebian.coreutils.
