Sally, Gene 3b1ec9fb81 kbuild: gen_init_cpio expands shell variables in file names ... Modify gen_init_cpio so that lines that specify files can contain what looks like a shell variable that's expanded during processing. For example: file /sbin/kinit ${RFS_BASE}/usr/src/klibc/kinit/kinit 0755 0 0 given RFS_BASE is "/some/directory" in the environment would be expanded to file /sbin/kinit /some/directory/usr/src/klibc/kinit/kinit 0755 0 0 If several environment variables appear in a line, they are all expanded with processing happening from left to right. Undefined variables expand to a null string. Syntax errors stop processing, letting the existing error handling show the user offending line. This patch helps embedded folks who frequently create several RFS directories and then switch between them as they're tuning an initramfs.
