However, ${srctree} contains an unescaped path to the source tree, which, when used in a sed substitution, makes sed complain: ++ sed 's/[^ ]* *//home/jeyu/jeyu-linux\/&/g' sed: -e expression #1, char 12: unknown option to `s' The sed substitution command 's' ends prematurely with the forward slashes in the pathname, and sed errors out when it encounters the 'h', which is an invalid sed substitution option. To avoid escaping forward slashes in ${srctree}, we can use '|' as an alternative delimiter for sed to avoid this error.

Ah yeah, I missed that. Thanks for catching that!
