[PATCH] fallback to hostname in scripts/package/builddeb

Show all headers | View raw

Hi,

I happened to build a kernel with "make deb-pkg" on a machine with no 
network connectivity, but this failed with:

[...]
  INSTALL debian/headertmp/usr/include/asm/ (65 files)
hostname: Name or service not known
../scripts/package/Makefile:90: recipe for target 'deb-pkg' failed
make[2]: *** [deb-pkg] Error 1

In scripts/package/builddeb it tries to construct an email address (that 
can be queried in /proc/version later on) but with no network, 
the "hostname -f" fails. The following patch falls back to just use the 
shortname if we cannot determine our FQDN.
