local.mk and SUDO

[Martyn Jago <martyn.jago@btinternet.com>]

I have a local.mk set up with my particular settings, and with SUDO
set to blank, as per the comment in default.mk:

,----[default.mk]
| # How to obtain administrative privileges
| # SUDO	= 	# leave blank if you don't need this
| SUDO	= sudo
`----

...since my org-mode files location doesn't require supervisor access
(typically I have 4 org-mode installs, and 4 Emacs versions for testing,
although currently I'm just running my working system).

However, when I've just gone to run `make up2' (awesome command by the
way), I get the error:

--8<---------------cut here---------------start------------->8---
> make up2
git remote update

After investigation it turns out the problem is a permissions issue:

--8<---------------cut here---------------start------------->8---
diff --git a/lisp/org-mobile.el b/lisp/org-mobile.el
old mode 100644
new mode 100755
--8<---------------cut here---------------end--------------->8---

After further investigation, I have modified git config to overide the
core.filemode setting which works for me:

,----
| core.fileMode
|        If false, the executable bit differences between the index and the
|        working copy are ignored; useful on broken filesystems like FAT.
|        See git-update-index(1). True by default.
`----

--8<---------------cut here---------------start------------->8---
git config core.filemode false
--8<---------------cut here---------------end--------------->8---


So really - this is just a heads-up of my experience setting SUDO to
blank, but it would be nice to know if this is expected behavior? If it
turns out that it is, then perhaps I can supply a documentation patch
(an extra comment in default.mk).

HTH
