Bug#526738: gratuitous use of subprocesses
Package: grub-pc
Version: 1.96+20090317-1
Severity: minor
Tags: upstream
File: /etc/grub.d/00_header
# sed -n 19,24p /etc/grub.d/00_header
transform=s,x,x,
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
grub_prefix=`echo /boot/grub | sed ${transform}`
What is it doing? That's two subprocesses (shell+sed) used for
absolutely zero purpose, as far as I can tell.

It's for these configure options
$ ./configure --help
Program names:
--program-prefix=PREFIXprepend PREFIX to installed program names
--program-suffix=SUFFIXappend SUFFIX to installed program names
--program-transform-name=PROGRAM run sed PROGRAM on installed program names
It's generated by the AC_ARG_PROGRAM autoconf macro [0]
I don't think it's that useful to remove that feature. Maybe some people
actually want to use it.
I doubt grub2 gets used on old 486 pcs or like that which are so slow that it
maybe matters.

Ah, so this is *after* the files have been processed by autoconf, so what's left in there is the autoconf-equivalent of NOOP. Thanks for the explanation. Feel free to do whatever you like with the bug report. ;) -- .''`. martin f. krafft madd...@d.o Related projects: : :' : proud Debian developer http://debiansystem.info `. `'` http://people.debian.org/~madduckhttp://vcs-pkg.org `- Debian - when you have better things to do than fixing systems the only difference between the saint and the sinner is that every saint has a past and every sinner has a future. -- oscar wilde digital_signature_gpg.asc Description: Digital signature (see http://martin-krafft.net/gpg/)
